Release Notes
- These notes are for ncurses 6.3, released October 21, 2021.
+ These notes are for ncurses 6.4, released December 31, 2022.
This release is designed to be source-compatible with ncurses 5.0
- through 6.2; providing extensions to the application binary interface
+ through 6.3; providing extensions to the application binary interface
(ABI). Although the source can still be configured to support the
ncurses 5 ABI, the reason for the release is to reflect improvements
to the ncurses 6 ABI and the supporting utility programs.
There are, of course, numerous other improvements, listed in this
announcement.
- The most important bug-fixes/improvements dealt with portability
+ The most important bug-fixes/improvements dealt with robustness
issues. The release notes also mention some other bug-fixes, but are
focused on new features and improvements to existing features since
- ncurses 6.2 release.
+ ncurses 6.3 release.
Library improvements
New features
- There are a few new features:
- * A new (experimental) driver, for the Windows Terminal
- configuration is provided.
- * A script is provided which enables OpenBSD users to upgrade their
- system to use ncurses 6.3 (OpenBSD developers are also invited to
- do this).
-
- Additionally, to improve performance other changes (and extensions)
- are provided in this release:
- * modify lib_mouse.c to check for out-of-range button numbers,
- convert those to position reports.
- * add sp-funcs for erasewchar, killwchar.
+ There are no new features in this release.
Other improvements
- These are revised features:
- * modify wgetnstr, wgetn_wstr to improve compatibility with SVr4
- curses in its treatment of interrupt and quit characters
-
- These were done to limit or ultimately deprecate features:
- * mark wgetch-events feature as deprecated.
- + prevent KEY_EVENT from appearing in curses.h unless the
- configure option --enable-wgetch-events is used.
- + modify MKkey_defs.sh to hide ncurses' definition of
- KEY_EVENTS to reduce Visual Studio C++ redefinition warnings.
- * reduce build-warnings by excluding ncurses-internals from
- deprecation warnings.
-
These are improvements to existing features:
- * drop symbols GCC_PRINTF and GCC_SCANF from <curses.h>, to simplify
- use.
- * apply gcc format attribute to prototypes which use a va_list
- parameter rather than a "..." variable-length parameter list.
- * modify <term.h> so that it is not necessary to include <curses.h>
- before <term.h>.
- * provide for wide-characters as background character in wbkgrnd
- * improve parameter-checking for tparm, adding function _nc_tiparm()
- to handle the most-used case, which accepts only numeric
- parameters.
- * use return-value from vsnprintf to reallocate as needed to allow
- for buffers larger than the screen size.
- * add another fflush(stdout) in _nc_flush to handle time-delays in
- the middle of strings such as flash when the application uses
- low-level calls rather than curses.
+ * modify delscreen to more effectively delete all windows on the
+ given screen.
+ * modify wnoutrefresh to call pnoutrefresh if its parameter is a
+ pad, rather than treating it as an error, and modify new_panel to
+ permit its window-parameter to be a pad
+ * modify curses_trace() to show the trace-mask as symbols, e.g.,
+ TRACE_ORDINARY, DEBUG_LEVEL(3).
+ * improve checks for valid mouse events when an intermediate mouse
+ state is not part of the mousemask specified by the caller
+ * allow extended-color number in opts parameter of wattr_on.
+ * improve _tracecchar_t2 formatting of base+combining character.
+ * trim out some unwanted linker options from ncurses*config and .pc
+ files seen in Fedora 36+.
+ * improve shell-scripts with shellcheck
+ * improve use of "trap" in shell scripts, using a script.
+ * modify make-tar.sh scripts to make timestamps more predictable.
These are corrections to existing features:
- * add a check to guard against repeat_char emitting digits which
- could be interpreted as BSD-style padding when --enable-bsdpad is
- configured.
- * check for screen size-change in scr_init and scr_restore, in case
- a screen dump does not match the current screen dimensions
+ * modify misc/gen-pkgconfig.in to allow for the case where the
+ library directory does not yet exist, since this is processed
+ before doing an install
+ * set trailing null on string passed from winsnstr to wins_nwstr.
+ * modify waddch_literal to allow for double-width base character
+ when merging a combining character
Program improvements
Several improvements were made to the utility programs:
- tabs
+ infocmp
- + implement "+m" option
+ + rewrite canonical_name function of infocmp to ensure buffer
+ size
+ + improve readability of long parameterized expressions with
+ the infocmp "-f" option by allowing split before a "%p"
+ marker.
+ + modify verbose-option of infocmp, tic, toe to enable
+ debug-tracing if that is configured.
- tic
+ tabs
+ limit tab-stop values to max-columns
- + add check for duplicate "use=" clauses.
- + add check to report instances where tparm would detect an
- error in an expression.
- + add user-defined capabilities from mintty to Caps-ncurses,
- for checking consistency.
- + improve warning when oc/op do not mention SGR 39/49 for xterm
- compatible XT flag.
- + improve checks for number of parameters of smglp, smgrp,
- smgtp, and smgbp.
- + improve "-c" option to validate the number and type of
- parameters and compare against expected number/type before
- deciding which set of parameter-lists to use in tparm calls.
- + improve check for errors detected in tparm.
- + improve format of output, to ensure that the messages contain
- only printable text.
- + modify to eliminate unnecessary "\" to escape ":" in terminfo
- format.
- + remove check that assumes that none or both parameterized and
- non-parameterized margin-setting capabilities are present.
-
- toe
-
- + modify output of "toe -as" to show first description found
- rather than the last.
- + add a check to ensure that a "termcap file" is text rather
- than binary.
+ tic
+ add consistency check in tic for u6/u7/u8/u9 and NQ
+ capabilities.
tput
-
- + modify to allow multiple commands per line.
- + improve parameter-checking by analyzing all extended string
- capabilities, e.g., as used in the Cs and Ms capabilities of
- the tmux description.
- + make warning messages consistently using alias names when
- those are used, rather than the underlying program's name.
- + improve usage message for aliases such as clear, by
- eliminating tput-specific portions.
- + modify initialization to avoid opening /dev/tty for cases
- other than reset/init, e.g., for clear.
+ corrected use of original tty-modes in init/reset subcommands
Examples
Along with the library and utilities, improvements were made to the
ncurses-examples. Most of this activity aimed at improving the
- test-packages. A few changes are more generally useful, e.g., for the
- main ncurses test-program, and for analyzing traces using the
- tracemunch script:
- * add "-r" option to the dots test-programs, to help with scripting
- a performance comparison.
- * build-fix for test_opaque, for configurations without opaque
- curses structs, e.g., ncurses 5.7.
- * improve tracemunch logic for "RUN" compaction.
- * improve tracemunch's coverage of form/menu/panel libraries.
- * improve tracemunch's checking/reporting the type for the first
- parameter, e.g., "WINDOW*" rather than "#1".
- * modify tracemunch and the panel library to show readable traces
- for panel- and user-pointers.
+ test-packages:
+ * add minimal -h (usage) and -V (version) getopt logic to all
+ ncurses-examples programs.
+ * fix an error in "@" command in test/ncurses.c F-menu
+ * add curses_trace to ifdef's for START_TRACE in test/test.priv.h
+ * improve pthread-configuration for test/worm.c
+ * add setlocale call to several test-programs.
+ * workaround in test/picsmap.c for use of floating point for rgb
+ values by ImageMagick 6.9.11, which appears to use the wrong upper
+ limit.
+ * use static libraries for AdaCurses test-package for Mageia, since
+ no gprbuild package is available.
+ * install Ada95 sample programs in libexecdir, adding a wrapper
+ script to invoke those.
+ * install ncurses-examples programs in libexecdir, adding a wrapper
+ script to invoke those.
There are other new demo/test programs and reusable examples:
- back_ground
- to exercise the wide-character background functions.
+ test/combine
+ demonstrate combining characters
+
+ test/test_delwin
+ demonstrate deleting a window
- move_field
- to demonstrate move_field, and a stub for a corresponding demo
- of dup_field.
+ test/test_mouse
+ observe mouse events in the raw terminal or parsed ncurses
+ modes
- test_tparm
- for checking tparm changes.
+ test/test_unget_wch
+ demonstrate the unget_wch and unget functions

+ ease adoption).
Documentation
features and show how they evolved, there are corrections,
clarifications, etc.:
* Corrections:
- + make opts extension for getcchar work as documented for
- ncurses 6.1, adding "-g" flag to demo_new_pair to illustrate.
- + modify tset "-q" option to refrain from modifying terminal
- modes, to match the documentation.
+ + remove a stray '/' from description of %g in terminfo(5).
+ + correct/improve font-formatting in curs_getch.3x, as well as
+ other manual pages.
* New/improved history and portability sections:
- + improve documentation for tparm and static/dynamic variables.
- + add history note to curs_scanw.3x for <stdarg.h> and
- <varargs.h>
- + add history note to curs_printw.3x for <stdarg.h> and
- <varargs.h>
- + add portability note to ncurses.3x regarding <stdarg.h>
- + add historical notes to tput, curses-terminfo and
- curses-color manpages based on source-code for SVr2, SVr3 and
- SVr4.
- + improve history section for tset manpage based on the 1BSD
- tarball, which preceded BSD's SCCS checkins by more than
- three years.
+ + add portability notes for delscreen and delwin in manual.
+ + improve curs_slk.3x discussion of extensions and portability
* Other improvements:
- + explain in ncurses.3x that functions in the tinfo library do
- not rely upon wide-characters.
- + improve manual page for panel library, extending the
- portability section as well as documenting error-returns.
- + add section on margins to terminfo.5, adapted from X/Open
- Curses.
- + improve man/term.5 section on legacy storage format.
- + add a note in terminfo.5 explaining that no-parameter strings
- such as sgr0 or cnorm should not be used with tparm.
- + improve description of BSD-style padding in curs_termcap.3x
- + improve discussion of padding versus tparm and tputs in
- man/curs_terminfo.3x
- + add a note in manual page to explain ungetch vs unget_wch.
- + improve description of error-returns in waddch and waddnstr
- manual pages.
+ + improve curs_bkgd.3x, explaining that bkgdset can affect
+ results for bkgd
+ + add note on portable memory-leak checking in curs_memleaks.3x
+ + expanded description in resizeterm.3x
+ + add section on releasing memory to curs_termcap.3x and
+ curs_terminfo.3x manpages.
+ + add clarification of the scope of dynamic variables in
+ terminfo(5).
+ + improve formatting of ncurses-intro.html and hackguide.html
+ + improve curs_clear.3x links to other pages
+ + update ncurses-howto, making documentation fixes along with
+ corrections to example programs.
+ + use newer version 1.36 of gnathtml for generating Ada html
+ files.
+ + update external links in Ada95.html
There are no new manual pages (all of the manual page updates are to
existing pages).
- Some of the improvements are more subtle, relating to the way the
- information is presented. For instance, hyphenation is suppressed in
- the HTML files generated from manual pages because an upgrade to groff
- gave noticeably poorer results, interfering with the process of
- creating links between the resulting webpages.
-
Interesting bug-fixes
- While there were many bugs fixed during development of ncurses 6.3,
+ While there were many bugs fixed during development of ncurses 6.4,
only a few (the reason for this release) were both important and
interesting. Most of the bug-fixes were for local issues which did not
affect compatibility across releases. Since those are detailed in the
NEWS file no elaboration is needed here.
- The interesting bugs were:
- * modify wbkgd and wbkgrnd to avoid storing a null in the background
- character, because it may be used in cases where the corresponding
- 0x80 is not treated as a null.
- This was a regression introduced in ncurses 6.2 (reported on the
- mailing list), for which the workaround was to specify a blank for
- the background character.
- * remove output-related checks for nl/nonl (also reported on the
- mailing list).
- * improve tparm implementation of %P and %g, more closely matching
- SVr4 terminfo. Those denote static and dynamic variables in
- terminfo expressions.
- Exactly what those terms meant was never documented before in any
- implementation of curses, aside from source code. Unlike the other
- two fixes, the problem was discovered while studying OpenBSD's
- version of tset.
+ The interesting bugs were those dealing with memory leaks and buffer
+ overflows. Although the utilities are designed for text files (which
+ they do properly), some choose to test them with non-text files.
+ * Text files contain no embedded nulls. Also, they end with a
+ newline. Feeding tic non-text files exposed a few cases where the
+ program did not check for those issues. As a result, further
+ processing of the input found limit-checks whose assumptions were
+ invalid.
+ * Fixing the limit-checks (first) found a problem with tic managing
+ the list of strings in a terminal description. In merging two
+ terminal descriptions (i.e., the "use=" feature), tic was not
+ allocating a complete copy. A quick repair for that introduced a
+ memory leak.
+ * The checks for non-text files are improved (i.e., embedded nulls
+ in the input file will cause tic to reject it rather than
+ attempting to process it).
+ * The string allocations in tic are likewise improved.
Configuration changes
Major changes
- There are no major changes. Several new options were added to ease
- integration of packages with systems using different versions of GNAT
- and ncurses. Also, improvements were made to configure checks.
+ There are no major changes. No new options were added. Several
+ improvements were made to configure checks.
Configuration options
There are a few new/modified configure options:
- --enable-fvisibility
- new configure option and check for gcc -fvisibility=hidden
- feature
-
- --enable-leaks
- corrected to allow turning leak-checking off later in a set of
- options.
-
- --enable-stdnoreturn
- new configure option makes the _Noreturn keyword optional to
- ease transition.
-
- --disable-pkg-ldflags
- revised option also controls whether $LDFLAGS from the build is
- provided in "-config" and ".pc" files.
-
- --disable-root-access
- add configure option which tells ncurses to disallow most
- file-opens by setuid processes.
+ --with-abi-version
+ add ABI 7 defaults to configure script.
- --disable-wattr-macros
- changed default to help packagers who reuse wide ncursesw
- header file with non-wide ncurses library.
+ --with-caps
+ add warning in configure script if file specified for
+ "--with-caps" does not exist.
- --with-pkg-config-libdir
- revised option uses the actual search path from pkg-config or
- pkgconf using the output from --debug.
+ --with-manpage-format
+ bzip2 and xz compression are now supported
- --with-ada-libname
- --with-form-libname
- --with-menu-libname
- --with-panel-libname
- new several --with-xxx-libname options, to help with pkgsrc
+ --with-xterm-kbs
+ add check/warning in configure script if option
+ "--with-xterm-kbs" is missing or inconsistent
Portability
Many of the portability changes are implemented via the configure
script:
- * add a special case in the configure script to work around one of
- the build-time breakages reported for OpenBSD 6 here:
-
- https://www.mail-archive.com/bugs@openbsd.org/msg13200.html
- * modify configure check for libtool to prevent accidental use of an
- OpenBSD program which uses the same name.
- * modify configuration checks for build-time tic/infocmp to use
- AC_CHECK_TOOL. That can still be overridden by --with-tic-path and
- --with-infocmp-path when fallbacks are used, but even if not using
- fallbacks, the improved check may help with cross-compiling.
- * relax modification-time comparison in CF_LINK_FUNCS to allow it to
- accept link() function with NFS filesystems which change the mtime
- on the link target, e.g., several BSD systems.
- * modify configure check for c89/c99 aliases of clang to use its
- -std option instead, because some platforms, in particular macOS,
- do not provide workable c89/c99 aliases.
- * modify CF_NCURSES_CONFIG to work around Xcode's c99 "-W" option,
- which conflicts with conventional use for passing linker options.
- * modify configure scripts to filter out redefinitions of
- _XOPEN_SOURCE, e.g., for NetBSD which generally supports 500, but
- 600 is needed for ncursesw.
+ * amend configure option's auto-search to account for systems where
+ none of the directories known to pkg-config exist
+ * corrected regex needed for older pkg-config used in Solaris 10
+ * improve handling of --with-pkg-config-libdir option, allowing for
+ the case where either $PKG_CONFIG_LIBDIR or the option value has a
+ colon-separated list of directories
+ * if the --with-pkg-config-libdir option is not given, use
+ ${libdir}/pkgconfig as a default
+ * improve search-path check for pkg-config, e.g., for Debian testing
+ which installs pkg-config with architecture-prefixes.
+ * build-fix for cross-compiling to MingW, conditionally add -lssp
+ * improve configure check for getttynam
+ * fixes to build with dietlibc:
+ + add configure check for fpathconf
+ + add configure check for math sine/cosine, needed in
+ test/tclock, and eliminate pow() from test/hanoi
+ + use wcsnlen as an alternative to wmemchr if it is not found
+ * modify configure macro CF_BUILD_CC to check if the build-compiler
+ works, rather than that it is different from the cross-compiler,
+ e.g., to accommodate a compiler which can be used for either
+ purpose with different flags
+ * modify configure/scripts to work around interference by GNU grep
+ 3.8
Here are some of the other portability fixes:
- * change configure-check and source-code for gcc's noreturn
- attribute to assume it is a prefix rather than suffix, matching
- c11's _Noreturn convention.
- * modify mk-1st.awk to account for extra-suffix configure option.
- * build-fix for termsort module when configured with termcap.
- * modify configure script and makefiles to support ".PHONY" make
- program feature.
- * amend libtool configuration to add dependency for install.tic,
- etc., in ncurses/Makefile on the lower-level libraries.
- * modify Ada95 source-generation utility to write to a file given as
- parameter rather than to the standard output, allowing builds with
- MinGW.
- * amend tic/infocmp check to allow for the respective tool's
- absence.
- * build-fixes for gnat 10.1.1, whose gnatmake drops integration with
- gprbuild.
- * correct configure version-check/warning for g++ to allow for 10.x
+ * change man_db.renames to template, to handle ncurses*-config
+ script with the --extra-suffix configure option.
+ * update CF_XOPEN_SOURCE macro, adding variants "gnueabi" and
+ "gnueabihf" to get _DEFAULT_SOURCE special case, as well as adding
+ GNU libc suffixes for "abi64", "abin32", "x32" to distinguish it
+ from other libc flavors.
+ * work around musl's nonstandard use of feature test macros by
+ adding a definition for NCURSES_WIDECHAR to the generated ".pc"
+ and *-config files.
+ * use "command -v" rather than "type" in Ada95/gen/Makefile.in to
+ fix a portability issue.

+ script.</p>
</li>
<li>

- 6.3, only a few (the reason for this release) were both important
+ 6.4, only a few (the reason for this release) were both important
and interesting. Most of the bug-fixes were for local issues
which did not affect compatibility across releases. Since those
are detailed in the <a href=
- "@HOMEPAGE@/NEWS.html#t20211018">NEWS</a> file no elaboration is
+ "@HOMEPAGE@/NEWS.html#t20221231">NEWS</a> file no elaboration is
needed here.</p>
- <p>The interesting bugs were:</p>
+ <p>The interesting bugs were those dealing with memory leaks and
+ buffer overflows. Although the utilities are designed for
+ <em>text</em> files (which they do properly), some choose to test
+ them with <strong>non-</strong><em>text</em> files.</p>
<ul>
<li>
- <p>modify <a href=
- "@HOMEPAGE@/man/curs_bkgd.3x.html#h3-bkgd">wbkgd</a> and
- <a href=
- "@HOMEPAGE@/man/curs_bkgrnd.3x.html#h3-bkgrnd">wbkgrnd</a> to
- avoid storing a null in the background character, because it
- may be used in cases where the corresponding 0x80 is not
- treated as a null.</p>
-
- <p>This was a regression introduced in ncurses 6.2 (<a href=
- "https://lists.gnu.org/archive/html/bug-ncurses/2020-03/msg00000.html">reported</a>
- on the mailing list), for which the workaround was to specify
- a blank for the background character.</p>
+ <p>Text files contain no embedded nulls. Also, they end with
+ a newline. Feeding <strong>tic</strong> non-text files
+ exposed a few cases where the program did not check for those
+ issues. As a result, further processing of the input found
+ limit-checks whose assumptions were invalid.</p>
</li>
<li>
- <p>remove output-related checks for <a href=
- "@HOMEPAGE@/man/curs_outopts.3x.html">nl/nonl</a> (also
- <a href=
- "https://lists.gnu.org/archive/html/bug-ncurses/2020-09/msg00018.html">
- reported</a> on the mailing list).</p>
+ <p>Fixing the limit-checks (first) found a problem with
+ <strong>tic</strong> managing the list of strings in a
+ terminal description. In merging two terminal descriptions
+ (i.e., the “use=” feature), <strong>tic</strong>
+ was not allocating a complete copy. A quick repair for that
+ introduced a memory leak.</p>
</li>
<li>
- <p>improve tparm implementation of <tt>%P</tt> and
- <tt>%g</tt>, more closely matching SVr4 terminfo. Those
- denote <em>static</em> and <em>dynamic</em> variables in
- terminfo expressions.</p>
+ <p>The checks for non-text files are improved (i.e., embedded
+ nulls in the input file will cause <strong>tic</strong> to
+ reject it rather than attempting to process it).</p>
+ </li>
- <p>Exactly what those terms meant was never documented before
- in any implementation of curses, aside from source code.
- Unlike the other two fixes, the problem was discovered while
- studying OpenBSD's version of <a href=
- "@HOMEPAGE@/ncurses-openbsd.html#issue_tput">tset</a>.</p>
+ <li>
+ <p>The string allocations in <strong>tic</strong> are
+ likewise improved.</p>
</li>

+Abstract
This document is a hacker's tour of the ncurses library and utilities.
It discusses design philosophy, implementation methods, and the
reading for anyone who is interested in porting, extending or
improving the package.
- Objective of the Package
+Objective of the Package
The objective of the ncurses package is to provide a free software API
for character-cell terminals and terminal emulators with the following
cannot add features if it means breaking the portion of the API
corresponding to historical curses versions.
-Why System V Curses?
+ Why System V Curses?
We used System V curses as a model, reverse-engineering their API, in
order to fulfill the first two objectives.
X/Open is explicitly and closely modeled on System V. So conformance
with System V took us most of the way to base-level XSI conformance.
-How to Design Extensions
+ How to Design Extensions
The third objective (standards conformance) requires that it be easy
to condition source code using ncurses so that the absence of
does not define, but which is defined in the ncurses library header.
You can use this to condition the calls to the mouse API calls.
- Portability and Configuration
+Portability and Configuration
Code written for ncurses may assume an ANSI-standard C compiler and
POSIX-compatible OS interface. It may also assume the presence of a
specification files (configure.in and aclocal.m4) to set up a new
feature macro, which you then use to condition your code.
- Documentation Conventions
+Documentation Conventions
There are three kinds of documentation associated with this package.
Each has a different preferred format:
Our conventions are simple:
1. Maintain package-internal files in plain text. The expected viewer
- for them more(1) or an editor window; there is no point in
+ for them is more(1) or an editor window; there is no point in
elaborate mark-up.
2. Mark up manual pages in the man macros. These have to be viewable
through traditional man(1) programs.
nice-looking printed version from it. Also, of course, it make
exporting things like the announcement document to WWW pretty trivial.
- How to Report Bugs
+How to Report Bugs
The reporting address for bugs is bug-ncurses@gnu.org. This is a
majordomo list; to join, write to bug-ncurses-request@gnu.org with a
comments of hardscroll.c and hashmap.c; then try it out. You can also
test the hardware-scrolling optimization separately with hardscroll.
- A Tour of the Ncurses Library
+A Tour of the Ncurses Library
-Library Overview
+ Library Overview
Most of the library is superstructure -- fairly trivial convenience
interfaces to a small set of basic functions and data structures used
We will discuss these in the compiler tour.
-The Engine Room
+ The Engine Room
- Keyboard Input
+ Keyboard Input
All ncurses input funnels through the function wgetch(), defined in
lib_getch.c. This function is tricky; it has to poll for keyboard and
value. The function timed_wait() effectively simulates a System V
select.
- Mouse Events
+ Mouse Events
If the mouse interface is active, wgetch() polls for mouse events each
call, before it goes to the keyboard for input. It is up to
accepted to parse the digested mouse reports (low-level events) into a
gesture (a high-level or composite event).
- Output and Screen Updating
+ Output and Screen Updating
With the single exception of character echoes during a wgetnstr() call
(which simulates cooked-mode line editing in an ncurses window), the
variable _nc_optimize_enable. See the file include/curses.h.in for
mask values, near the end.
- The Forms and Menu Libraries
+The Forms and Menu Libraries
The forms and menu libraries should work reliably in any environment
you can port ncurses to. The only portability issue anywhere in them
panels support; u386mon 2.10 and beyond use it. This version has been
slightly cleaned up for ncurses.
- A Tour of the Terminfo Compiler
+A Tour of the Terminfo Compiler
The ncurses implementation of tic is rather complex internally; it has
to do a trying combination of missions. This starts with the fact
the grammar above it is trivial, just "parse entries till you run out
of file".
-Translation of Non-use Capabilities
+ Translation of Non-use Capabilities
Translation of most things besides use capabilities is pretty
straightforward. The lexical analyzer's tokenizer hands each
of adding one line to the include/Caps file. We will have more to say
about this in the section on Source-Form Translation.
-Use Capability Resolution
+ Use Capability Resolution
The background problem that makes tic tricky is not the capability
translation itself, it is the resolution of use capabilities. Older
complain about overwriting entries newly made during the tic run, but
not about overwriting ones that predate it.
-Source-Form Translation
+ Source-Form Translation
Another use of tic is to do source translation between various termcap
and terminfo formats. There are more variants out there than you might
for example, is where the AIX box1 capability get translated to an
acsc string.
- Other Utilities
+Other Utilities
The infocmp utility is just a wrapper around the same entry-dumping
code used by tic for source translation. Perhaps the one interesting
The tput and clear utilities just do an entry load followed by a
tputs() of a selected capability.
- Style Tips for Developers
+Style Tips for Developers
See the TO-DO file in the top-level directory of the source
distribution for additions that would be particularly useful.
Have fun!
- Porting Hints

The following notes are intended to be a first step towards DOS and
Macintosh ports of the ncurses libraries.

<p>Along with the library and utilities, improvements were made
to the <a href=
- "https://invisible-island.net/ncurses/ncurses-examples.html">ncurses-examples</a>.
- Most of this activity aimed at improving the test-packages. A few
- changes are more generally useful, e.g., for the main ncurses
- test-program, and for analyzing traces using the
- <em>tracemunch</em> script:</p>
+ "https://invisible-island.net/ncurses/ncurses-examples.html">ncurses-examples</a>. Most of
+ this activity aimed at improving the test-packages:</p>
<ul>
<li>
- <p>add “<tt>-r</tt>” option to the <em>dots</em>
- test-programs, to help with scripting a performance
- comparison.</p>
+ <p>add minimal <tt>-h</tt> (usage) and <tt>-V</tt> (version)
+ getopt logic to all ncurses-examples programs.</p>
+ </li>
+
+ <li>
+ <p>fix an error in "@" command in <tt>test/ncurses.c</tt>
+ F-menu</p>
</li>
<li>
- <p>build-fix for <em>test_opaque</em>, for configurations
- without opaque curses structs, e.g., ncurses 5.7.</p>
+ <p>add curses_trace to ifdef's for <tt>START_TRACE</tt> in
+ <tt>test/test.priv.h</tt></p>
</li>
<li>
- <p>improve <em>tracemunch</em> logic for "RUN"
- compaction.</p>
+ <p>improve pthread-configuration for test/worm.c</p>
</li>
<li>
- <p>improve <em>tracemunch</em>'s coverage of form/menu/panel
- libraries.</p>
+ <p>add <tt>setlocale</tt> call to several test-programs.</p>
</li>
<li>
- <p>improve <em>tracemunch</em>'s checking/reporting the type
- for the first parameter, e.g., "WINDOW*" rather than
- "#1".</p>
+ <p>workaround in <tt>test/picsmap.c</tt> for use of floating
+ point for rgb values by ImageMagick 6.9.11, which appears to
+ use the wrong upper limit.</p>
</li>
<li>
- <p>modify <em>tracemunch</em> and the panel library to show
- readable traces for panel- and user-pointers.</p>
+ <p>use static libraries for AdaCurses test-package for

<h3><a name="h3-bug-fixes" id="h3-bug-fixes">Interesting
bug-fixes</a></h3>
<p>While there were many bugs fixed during development of ncurses
- 6.3, only a few (the reason for this release) were both important
+ 6.4, only a few (the reason for this release) were both important
and interesting. Most of the bug-fixes were for local issues
which did not affect compatibility across releases. Since those
are detailed in the <a href=
- "https://invisible-island.net/ncurses/NEWS.html#t20211018">NEWS</a>
- file no elaboration is needed here.</p>
+ "https://invisible-island.net/ncurses/NEWS.html#t20221231">NEWS</a> file no elaboration is
+ needed here.</p>
- <p>The interesting bugs were:</p>
+ <p>The interesting bugs were those dealing with memory leaks and
+ buffer overflows. Although the utilities are designed for
+ <em>text</em> files (which they do properly), some choose to test
+ them with <strong>non-</strong><em>text</em> files.</p>
<ul>
<li>
- <p>modify <a href=
- "https://invisible-island.net/ncurses/man/curs_bkgd.3x.html#h3-bkgd">
- wbkgd</a> and <a href=
- "https://invisible-island.net/ncurses/man/curs_bkgrnd.3x.html#h3-bkgrnd">
- wbkgrnd</a> to avoid storing a null in the background
- character, because it may be used in cases where the
- corresponding 0x80 is not treated as a null.</p>
-
- <p>This was a regression introduced in ncurses 6.2 (<a href=
- "https://lists.gnu.org/archive/html/bug-ncurses/2020-03/msg00000.html">reported</a>
- on the mailing list), for which the workaround was to specify
- a blank for the background character.</p>
+ <p>Text files contain no embedded nulls. Also, they end with
+ a newline. Feeding <strong>tic</strong> non-text files
+ exposed a few cases where the program did not check for those
+ issues. As a result, further processing of the input found
+ limit-checks whose assumptions were invalid.</p>
</li>
<li>
- <p>remove output-related checks for <a href=
- "https://invisible-island.net/ncurses/man/curs_outopts.3x.html">
- nl/nonl</a> (also <a href=
- "https://lists.gnu.org/archive/html/bug-ncurses/2020-09/msg00018.html">
- reported</a> on the mailing list).</p>
+ <p>Fixing the limit-checks (first) found a problem with
+ <strong>tic</strong> managing the list of strings in a
+ terminal description. In merging two terminal descriptions
+ (i.e., the “use=” feature), <strong>tic</strong>
+ was not allocating a complete copy. A quick repair for that
+ introduced a memory leak.</p>
</li>
<li>
- <p>improve tparm implementation of <tt>%P</tt> and
- <tt>%g</tt>, more closely matching SVr4 terminfo. Those
- denote <em>static</em> and <em>dynamic</em> variables in
- terminfo expressions.</p>
+ <p>The checks for non-text files are improved (i.e., embedded
+ nulls in the input file will cause <strong>tic</strong> to
+ reject it rather than attempting to process it).</p>
+ </li>
- <p>Exactly what those terms meant was never documented before
- in any implementation of curses, aside from source code.
- Unlike the other two fixes, the problem was discovered while
- studying OpenBSD's version of <a href=
- "https://invisible-island.net/ncurses/ncurses-openbsd.html#issue_tput">
- tset</a>.</p>
+ <li>
+ <p>The string allocations in <strong>tic</strong> are
+ likewise improved.</p>
</li>
</ul>

</li>
<li>
- <p>modify configuration checks for build-time tic/infocmp to

+Introduction
This document is an introduction to programming with curses. It is not
an exhaustive reference for the curses Application Programming
will typically be a great deal simpler and less expensive than one
using an X toolkit.
-A Brief History of Curses
+ A Brief History of Curses
Historically, the first ancestor of curses was the routines written to
provide screen-handling for the vi editor; these used the termcap
releases, curses evolved to use more facilities and offer more
capabilities, going far beyond BSD curses in power and flexibility.
-Scope of This Document
+ Scope of This Document
This document describes ncurses, a free implementation of the System V
curses API with some clearly marked extensions. It includes the
extension libraries, also cloned from System V, which support easy
construction and sequences of menus and fill-in forms.
-Terminology
+ Terminology
In this document, the following terminology is used with reasonable
consistency:
The package's idea of what the terminal display currently looks
like, i.e., what the user sees now. This is a special screen.
- The Curses Library
+The Curses Library
-An Overview of Curses
+ An Overview of Curses
- Compiling Programs using Curses
+ Compiling Programs using Curses
In order to use the library, it is necessary to have certain types and
variables defined. Therefore, the programmer must have a line:
your LDFLAGS or on the command line. There is no need for any other
libraries.
- Updating the Screen
+ Updating the Screen
In order to update the screen optimally, it is necessary for the
routines to know what the screen currently looks like and what the
package implementation determine the most efficient way to repaint the
screen.
- Standard Windows and Function Naming Conventions
+ Standard Windows and Function Naming Conventions
As hinted above, the routines can use several windows, but two are
automatically given: curscr, which knows what the terminal looks like,
(y, x) coordinates. If a function requires a window pointer, it is
always the first parameter passed.
- Variables
+ Variables
The curses library sets some variables describing the terminal
capabilities.

Now we describe how to actually use the screen package. In it, we
assume all updating, reading, etc. is applied to stdscr. These

- Starting up
+ Starting up
In order to use the screen package, the routines must know about
terminal characteristics, and the space for curscr and stdscr must be
of old windows. All the options described above can be applied to any
window.
- Output
+ Output
Now that we have set things up, we will want to actually update the
terminal. The basic functions used to change what will go on a window
implementing a command which would redraw the screen in case it get
messed up.
- Input
+ Input
The complementary function to addch() is getch() which, if echo is
set, will call addch() to echo the character. Since the screen package
curses.h The mapping from sequences to #define values is determined by
key_ capabilities in the terminal's terminfo entry.
- Using Forms Characters
+ Using Forms Characters
The addch() function (and some others, including box() and border())
can accept some pseudo-character arguments which are specially defined
the terminal does not have such characters, curses.h will map them to
a recognizable (though ugly) set of ASCII defaults.
- Character Attributes and Color
+ Character Attributes and Color
The ncurses package supports screen highlights including standout,
reverse-video, underline, and blink. It also supports color, which is
combination. Note that COLOR_PAIR(N), for constant N, is itself a
compile-time constant and can be used in initializers.
- Mouse Interfacing
+ Mouse Interfacing
The ncurses library also provides a mouse interface.
See the manual page curs_mouse(3X) for full details of the
mouse-interface functions.
- Finishing Up
+ Finishing Up
In order to clean up after the ncurses routines, the routine endwin()
is provided. It restores tty modes to what they were when initscr()
Thus, anytime after the call to initscr, endwin() should be called
before exiting.
-Function Descriptions
+ Function Descriptions
We describe the detailed behavior of some important curses functions
here, as a supplement to the manual page descriptions.
- Initialization and Wrapup
+ Initialization and Wrapup
initscr()
The first function called should almost always be initscr().
The inverse of newterm(); deallocates the data structures
associated with a given SCREEN reference.
- Causing Output to the Terminal
+ Causing Output to the Terminal
refresh() and wrefresh(win)
These functions must be called to actually get any output on
with fewer total characters transmitted (this also avoids a
visually annoying flicker at each update).
- Low-Level Capability Access
+ Low-Level Capability Access
setupterm(term, filenum, errret)
This routine is called to initialize a terminal's description,
array ttytype[]. Subsequent calls to setupterm() will overwrite
this array, so you will have to save it yourself if need be.

single-line pseudo-operations. These pseudo-ops can be distinguished
by the fact that they are named in capital letters.
-Hints, Tips, and Tricks
+ Hints, Tips, and Tricks
The ncurses manual pages are a complete reference for this library. In
the remainder of this document, we discuss various useful methods that
may not be obvious from the manual page descriptions.
- Some Notes of Caution
+ Some Notes of Caution
If you find yourself thinking you need to use noraw() or nocbreak(),
think again and move carefully. It is probably better design to use
in an environment with window resizes, in which case several screens
could be open with different sizes.
- Temporarily Leaving NCURSES Mode
+ Temporarily Leaving NCURSES Mode
Sometimes you will want to write a program that spends most of its
time in screen mode, but occasionally returns to ordinary "cooked"
addstr("returned.\n"); /* prepare return message */
refresh(); /* restore save modes, repaint screen */
- Using NCURSES under XTERM
+ Using NCURSES under XTERM
A resize operation in X sends SIGWINCH to the application running
under xterm. The easiest way to handle SIGWINCH is to do an endwin,
it cannot know how you want the screen re-painted. You will usually
have to write special-purpose code to handle KEY_RESIZE yourself.
- Handling Multiple Terminal Screens
+ Handling Multiple Terminal Screens
The initscr() function actually calls a function named newterm() to do
most of its work. If you are writing a program that opens multiple
with the set_term call. Note that you will also have to call
def_shell_mode and def_prog_mode on each tty yourself.
- Testing for Terminal Capabilities
+ Testing for Terminal Capabilities
Sometimes you may want to write programs that test for the presence of
various capabilities before deciding whether to go into ncurses mode.
can include the term.h file and test the value of the macro
cursor_address.
- Tuning for Speed
+ Tuning for Speed
Use the addchstr() family of functions for fast screen-painting of
text when you know the text does not contain any control characters.
Try to make attribute changes infrequent on your screens. Do not use
the immedok() option!
- Special Features of NCURSES
+ Special Features of NCURSES
The wresize() function allows you to resize a window in place. The
associated resizeterm() function simplifies the construction of
8. While most terminals which provide color allow only 8 colors, about
a quarter (including XFree86 xterm) support 16 colors.
-Compatibility with Older Versions
+ Compatibility with Older Versions
Despite our best efforts, there are some differences between ncurses
and the (undocumented!) behavior of older curses implementations.
These arise from ambiguities or omissions in the documentation of the
API.
- Refresh of Overlapping Windows
+ Refresh of Overlapping Windows
If you define two windows A and B that overlap, and then alternately
scribble on and refresh them, the changes made to the overlapping
you have defined. Then you can do one doupdate() and there will be a
single burst of physical I/O that will do all your updates.
- Background Erase
+ Background Erase
If you have been using a very old versions of ncurses (1.8.7 or older)
you may be surprised by the behavior of the erase functions. In older
This change in behavior conforms ncurses to System V Release 4 and the
XSI Curses standard.
-XSI Curses Conformance
+ XSI Curses Conformance
The ncurses library is intended to be base-level conformant with the
XSI Curses standard from X/Open. Many extended-level features (in
have a corresponding function which may be linked (and will be
prototype-checked) if the macro definition is disabled with #undef.
- The Panels Library
+The Panels Library
The ncurses library by itself provides good support for screen
displays in which the windows are tiled (non-overlapping). In the more
The panel library first appeared in AT&T System V. The version
documented here is the panel code distributed with ncurses.
-Compiling With the Panels Library
+ Compiling With the Panels Library
Your panels-using modules must import the panels library declarations
with
-lncurses. Many linkers are two-pass and will accept either order, but
it is still good practice to put -lpanel first and -lncurses second.
-Overview of Panels
+ Overview of Panels
A panel object is a window that is implicitly treated as part of a
deck including all other panel objects. The deck has an implicit
write, you will generate a lot of unnecessary refresh activity and
screen flicker.
-Panels, Input, and the Standard Screen
+ Panels, Input, and the Standard Screen
You should not mix wnoutrefresh() or wrefresh() operations with panels
code; this will work only if the argument window is either in the top
There is presently no way to display changes to one obscured panel
without repainting all panels.
-Hiding Panels
+ Hiding Panels
It is possible to remove a panel from the deck temporarily; use
hide_panel for this. Use show_panel() to render it visible again. The
or bottom_panel on a hidden panel(). Other panels operations are
applicable.
-Miscellaneous Other Facilities
+ Miscellaneous Other Facilities
It is possible to navigate the deck using the functions panel_above()
and panel_below. Handed a panel pointer, they return the panel above
code, to which you can attach application data. See the man page
documentation of set_panel_userptr() and panel_userptr for details.
- The Menu Library
+The Menu Library
A menu is a screen display that assists the user to choose some subset
of a given set of items. The menu library is a curses extension that
The menu library first appeared in AT&T System V. The version
documented here is the menu code distributed with ncurses.
-Compiling With the menu Library
+ Compiling With the menu Library
Your menu-using modules must import the menu library declarations with
#include <menu.h>
-lncurses. Many linkers are two-pass and will accept either order, but
it is still good practice to put -lmenu first and -lncurses second.
-Overview of Menus
+ Overview of Menus
The menus created by this library consist of collections of items
including a name string part and a description string part. To make
9. Free the items using free_item().

-Menu Display
+ Menu Display
The menu library calculates a minimum display size for your window,
based on the following variables:
have reasonable defaults which the library allows you to change (see
the menu_attribs(3x) manual page.
-Menu Windows
+ Menu Windows
Each menu has, as mentioned previously, a pair of associated windows.
Both these windows are painted when the menu is posted and erased when
these actually modifies the screen. To do that, call wrefresh() or
some equivalent.
-Processing Menu Input
+ Processing Menu Input
The main loop of your menu-processing code should call menu_driver()
repeatedly. The first argument of this routine is a menu pointer; the
considered application-specific commands. The menu_driver() code
ignores them and returns E_UNKNOWN_COMMAND.
-Miscellaneous Other Features
+ Miscellaneous Other Features
Various menu options can affect the processing and visual appearance
and input processing of menus. See menu_opts(3x) for details.
Each item, and each menu, has an associated user pointer on which you
can hang application data. See mitem_userptr(3x) and menu_userptr(3x).
- The Forms Library
+The Forms Library
The form library is a curses extension that supports easy programming
of on-screen forms for data entry and program control.
The form library first appeared in AT&T System V. The version
documented here is the form code distributed with ncurses.
-Compiling With the form Library
+ Compiling With the form Library
Your form-using modules must import the form library declarations with
#include <form.h>
-lncurses. Many linkers are two-pass and will accept either order, but
it is still good practice to put -lform first and -lncurses second.
-Overview of Forms
+ Overview of Forms
A form is a collection of fields; each field may be either a label
(explanatory text) or a data-entry location. Long forms may be
operations, the menu driver loop has to support field editing and data
validation.
-Creating and Freeing Fields and Forms
+ Creating and Freeing Fields and Forms
The basic function for creating fields is new_field():
FIELD *new_field(int height, int width, /* new field size */
to a form, but not vice-versa; thus, you will generally free your form
objects first.
-Fetching and Changing Field Attributes
+ Fetching and Changing Field Attributes
Each form field has a number of location and size attributes
associated with it. There are other field attributes used to control
to mean this field. Changes to it persist as defaults until your forms
application terminates.
- Fetching Size and Location Data
+ Fetching Size and Location Data
You can retrieve field sizes and locations through:
int field_info(FIELD *field, /* field from which to fetch */
size and location attributes of a new field, it fetches them from an
existing one.
- Changing the Field Location
+ Changing the Field Location
It is possible to move a field's location on the screen:
int move_field(FIELD *field, /* field to alter */
You can, of course. query the current location through field_info().
- The Justification Attribute
+ The Justification Attribute
One-line fields may be unjustified, justified right, justified left,
or centered. Here is how you manipulate this attribute:
preprocessor macros NO_JUSTIFICATION, JUSTIFY_RIGHT, JUSTIFY_LEFT, or
JUSTIFY_CENTER.
- Field Display Attributes
+ Field Display Attributes
For each field, you can set a foreground attribute for entered
characters, a background attribute for the entire field, and a pad
etc). The page bit of a field controls whether it is displayed at the
start of a new form screen.
- Field Option Bits
+ Field Option Bits
There is also a large collection of field option bits you can set to
control various aspects of forms processing. You can manipulate them
The option values are bit-masks and can be composed with logical-or in
the obvious way.
-Field Status
+ Field Status
Every field has a status flag, which is set to FALSE when the field is
created and TRUE when the value in field buffer 0 changes. This flag
initialization or termination hooks, or (3) just after a
REQ_VALIDATION request has been processed by the forms driver.
-Field User Pointer
+ Field User Pointer
Each field structure contains one character pointer slot that is not
used by the forms library. It is intended to be used by applications
field is created, the default-field user pointer is copied to
initialize the new field's user pointer.
-Variable-Sized Fields
+ Variable-Sized Fields
Normally, a field is fixed at the size specified for it at creation
time. If, however, you turn off its O_STATIC bit, it becomes dynamic
the field; use dynamic_field_info() to get the actual dynamic
size.
-Field Validation
+ Field Validation
By default, a field will accept any data that will fit in its input
buffer. However, it is possible to attach a validation type to a
Here are the pre-defined validation types:
- TYPE_ALPHA
+ TYPE_ALPHA
This field type accepts alphabetic data; no blanks, no digits, no
special characters (this is checked at character-entry time). It is
width, the validation check will always fail. A minimum width of zero
makes field completion optional.
- TYPE_ALNUM
+ TYPE_ALNUM
This field type accepts alphabetic data and digits; no blanks, no
special characters (this is checked at character-entry time). It is
greater than the field width, the validation check will always fail. A
minimum width of zero makes field completion optional.
- TYPE_ENUM
+ TYPE_ENUM
This type allows you to restrict a field's values to be among a
specified set of string values (for example, the two-letter postal
The REQ_NEXT_CHOICE and REQ_PREV_CHOICE input requests can be
particularly useful with these fields.
- TYPE_INTEGER
+ TYPE_INTEGER
This field type accepts an integer. It is set up as follows:
int set_field_type(FIELD *field, /* field to alter */
A TYPE_INTEGER value buffer can conveniently be interpreted with the C
library function atoi(3).
- TYPE_NUMERIC
+ TYPE_NUMERIC
This field type accepts a decimal number. It is set up as follows:
int set_field_type(FIELD *field, /* field to alter */
A TYPE_NUMERIC value buffer can conveniently be interpreted with the C
library function atof(3).
- TYPE_REGEXP
+ TYPE_REGEXP
This field type accepts data matching a regular expression. It is set
up as follows:
The syntax for regular expressions is that of regcomp(3). The check
for regular-expression match is performed on exit.
-Direct Field Buffer Manipulation
+ Direct Field Buffer Manipulation
The chief attribute of a field is its buffer contents. When a form has
been completed, your application usually needs to know the state of
or form's initialization or termination hooks, or (3) just after a
REQ_VALIDATION request has been processed by the forms driver.
-Attributes of Forms
+ Attributes of Forms
As with field attributes, form attributes inherit a default from a
system default form structure. These defaults can be queried or set by
connected to a given from. It returns -1 if the form-pointer argument
is NULL.
-Control of Form Display
+ Control of Form Display
In the overview section, you saw that to display a form you normally
start by defining its size (and fields), posting it, and refreshing
before handing control back to the forms driver in order to
re-synchronize it.
-Input Processing in the Forms Driver
+ Input Processing in the Forms Driver
The function form_driver() handles virtualized input requests for form
navigation, editing, and validation requests, just as menu_driver does
field-termination functions) with which your application code can
check that the input taken by the driver matched what was expected.
- Page Navigation Requests
+ Page Navigation Requests
These requests cause page-level moves through the form, triggering
display of a new form screen.
the last page goes to the first, and REQ_PREV_PAGE from the first page
goes to the last.
- Inter-Field Navigation Requests
+ Inter-Field Navigation Requests
These requests handle navigation between fields on the same page.
only if A, B, and C all share the same first line; otherwise it will
skip over B to C.
- Intra-Field Navigation Requests
+ Intra-Field Navigation Requests
These requests drive movement of the edit cursor within the currently
selected field.
whitespace. The commands to move to beginning and end of line or field
look for the first or last non-pad character in their ranges.
- Scrolling Requests
+ Scrolling Requests
Fields that are dynamic and have grown and fields explicitly created
with offscreen rows are scrollable. One-line fields scroll
For scrolling purposes, a page of a field is the height of its visible
part.
- Editing Requests
+ Editing Requests
When you pass the forms driver an ASCII character, it is treated as a
request to add the character to the field's data buffer. Whether this
See Form Options for discussion of how to set and clear the overload
options.
- Order Requests
+ Order Requests
If the type of your field is ordered, and has associated functions for
getting the next and previous values of the type from a given value,
Custom Validation Types), you can associate our own ordering
functions.
- Application Commands
+ Application Commands
Form requests are represented as integers above the curses value
greater than KEY_MAX and less than or equal to the constant
MAX_COMMAND. If your input-virtualization routine returns a value
above MAX_COMMAND, the forms driver will ignore it.
-Field Change Hooks
+ Field Change Hooks
It is possible to set function hooks to be executed whenever the
current field or form changes. Here are the functions that support
You can disable any of these hooks by (re)setting them to NULL, the
default value.
-Field Change Commands
+ Field Change Commands
Normally, navigation through the form will be driven by the user's
input requests. But sometimes it is useful to be able to move the
The initial page of a newly-created form is 0. The function
set_form_fields() resets this.
-Form Options
+ Form Options
Like fields, forms may have control option bits. They can be changed
or queried with these functions:
The option values are bit-masks and can be composed with logical-or in
the obvious way.
-Custom Validation Types
+ Custom Validation Types
The form library gives you the capability to define custom validation
types of your own. Further, the optional additional arguments of
with the handling of the additional arguments within custom validation
functions.
- Union Types
+ Union Types
The simplest way to create a custom data type is to compose it from
two preexisting ones:
first type, then for the second, to figure what type the buffer
contents should be treated as.
- New Field Types
+ New Field Types
To create a field type from scratch, you need to specify one or both
of the following things:
argument. It too should return TRUE if the character is valid, FALSE
otherwise.
- Validation Function Arguments
+ Validation Function Arguments
Your field- and character- validation functions will be passed a
second argument as well. This second argument is the address of a
functions should never see a NULL file pointer and need not check
specially for it.
- Order Functions For Custom Types
+ Order Functions For Custom Types
Some custom field types are simply ordered in the same well-defined
way that TYPE_ENUM is. For such types, it is possible to define
success (a legal next or previous value was set) or FALSE to indicate
failure.
- Avoiding Problems
+ Avoiding Problems
The interface for defining custom types is complicated and tricky.
Rather than attempting to create a custom type entirely from scratch,
