+ The <EM>ncurses</EM> library routines give the user a terminal-independent
+ method of updating character screens with reasonable optimization.
+ This implementation is "new curses" (<EM>ncurses</EM>) and is the approved
+ replacement for 4.4BSD classic curses, which has been discontinued.
+ This describes <EM>ncurses</EM> version 6.4 (patch 20240302).
+
+ The <EM>ncurses</EM> library emulates the curses library of System V Release 4
+ Unix ("SVr4"), and XPG4 (X/Open Portability Guide) curses (also known
+ as XSI curses). XSI stands for X/Open System Interfaces Extension.
+ The <EM>ncurses</EM> library is freely redistributable in source form.
+
+ <EM>ncurses</EM> man pages employ several sections to clarify matters of usage
+ and interoperability with other <EM>curses</EM> implementations.
+
+ <STRONG>o</STRONG> "NOTES" describes matters and caveats of which any user of the
+ <EM>ncurses</EM> API should be aware, such as limitations on the size of an
+ underlying integral type or the availability of a preprocessor
+ macro exclusive of a function definition (which prevents its
+ address from being taken). This section also describes
+ implementation details that will be significant to the programmer
+ but which are not standardized.
+
+ <STRONG>o</STRONG> "EXTENSIONS" presents <EM>ncurses</EM> innovations beyond the X/Open Curses
+ standard and/or the SVr4 <EM>curses</EM> implementation. They are termed
+ <EM>extensions</EM> to indicate that they cannot be implemented solely by
+ using the library API, but require access to the library's internal
+ state.
+
+ <STRONG>o</STRONG> "PORTABILITY" discusses matters (beyond the exercise of extensions)
+ that should be considered when writing to a <EM>curses</EM> standard, or to
+ multiple implementations.
+
+ <STRONG>o</STRONG> "HISTORY" examines points of detail in <EM>ncurses</EM> and other <EM>curses</EM>
+ implementations over the decades of their development, particularly
+ where precedent or inertia have frustrated better design (and, in a
+ few cases, where such inertia has been overcome).
+
+ A program using these routines must be linked with the <STRONG>-lncurses</STRONG>
+ option, or (if it has been generated) with the debugging library
+ <STRONG>-lncurses_g</STRONG>. (Your system integrator may also have installed these
+ libraries under the names <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>.) The ncurses_g
+ library generates trace logs (in a file called "trace" in the current
+ directory) that describe curses actions. See section "ALTERNATE
+ CONFIGURATIONS" below.
+
+ The <EM>ncurses</EM> package supports: overall screen, window and pad
+ manipulation; output to windows and pads; reading terminal input;
+ control over terminal and <STRONG>curses</STRONG> input and output options; environment
+ query routines; color manipulation; use of soft label keys; terminfo
+ capabilities; and access to low-level terminal-manipulation routines.
+
+
+</PRE><H3><a name="h3-Initialization">Initialization</a></H3><PRE>
+ The library uses the locale which the calling program has initialized.
+ That is normally done with <STRONG>setlocale(3)</STRONG>:
+
+ <STRONG>setlocale(LC_ALL,</STRONG> <STRONG>"");</STRONG>
+
+ If the locale is not initialized, the library assumes that characters
+ are printable as in ISO-8859-1, to work with certain legacy programs.
+ You should initialize the locale and not rely on specific details of
+ the library when the locale has not been set up.
+
+ The function <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> must be called to initialize the
+ library before any of the other routines that deal with windows and
+ screens are used. The routine <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> must be called before
+ exiting.
+
+ To get character-at-a-time input without echoing (most interactive,
+ screen oriented programs want this), the following sequence should be
used:
- <B>initscr();</B> <B>cbreak();</B> <B>noecho();</B>
+ <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
Most programs would additionally use the sequence:
- <B>nonl();</B>
- <B>intrflush(stdscr,</B> <B>FALSE);</B>
- <B>keypad(stdscr,</B> <B>TRUE);</B>
-
- Before a <B>curses</B> program is run, the tab stops of the
- terminal should be set and its initialization strings, if
- defined, must be output. This can be done by executing
- the <B>tput</B> <B>init</B> command after the shell environment variable
- <B>TERM</B> has been exported. <B>tset(1)</B> is usually responsible
- for doing this. [See <B><A HREF="terminfo.5.html">terminfo(5)</A></B> for further details.]
-
- The <B>ncurses</B> library permits manipulation of data
- structures, called <I>windows</I>, which can be thought of as
- two-dimensional arrays of characters representing all or
- part of a CRT screen. A default window called <B>stdscr</B>,
- which is the size of the terminal screen, is supplied.
- Others may be created with <B>newwin</B>.
-
- Note that <B>curses</B> does not handle overlapping windows,
- that's done by the <B><A HREF="panel.3x.html">panel(3x)</A></B> library. This means that you
- can either use <B>stdscr</B> or divide the screen into tiled
- windows and not using <B>stdscr</B> at all. Mixing the two will
- result in unpredictable, and undesired, effects.
-
- Windows are referred to by variables declared as <B>WINDOW</B> <B>*</B>.
- These data structures are manipulated with routines
- described here and elsewhere in the <B>ncurses</B> manual pages.
- Among which the most basic routines are <B>move</B> and <B>addch</B>.
- More general versions of these routines are included with
- names beginning with <B>w</B>, allowing the user to specify a
- window. The routines not beginning with <B>w</B> affect <B>stdscr</B>.)
-
- After using routines to manipulate a window, <B>refresh</B> is
- called, telling <B>curses</B> to make the user's CRT screen look
- like <B>stdscr</B>. The characters in a window are actually of
- type <B>chtype</B>, (character and attribute data) so that other
- information about the character may also be stored with
- each character.
-
- Special windows called <I>pads</I> may also be manipulated.
- These are windows which are not constrained to the size of
- the screen and whose contents need not be completely
- displayed. See <B><A HREF="curs_pad.3x.html">curs_pad(3x)</A></B> for more information.
-
- In addition to drawing characters on the screen, video
- attributes and colors may be supported, causing the
- characters to show up in such modes as underlined, in
- reverse video, or in color on terminals that support such
- display enhancements. Line drawing characters may be
- specified to be output. On input, <B>curses</B> is also able to
- translate arrow and function keys that transmit escape
- sequences into single values. The video attributes, line
- drawing characters, and input values use names, defined in
- <B><curses.h></B>, such as <B>A_REVERSE</B>, <B>ACS_HLINE</B>, and <B>KEY_LEFT</B>.
-
- If the environment variables <B>LINES</B> and <B>COLUMNS</B> are set, or
- if the program is executing in a window environment, line
- and column information in the environment will override
- information read by <I>terminfo</I>. This would effect a program
- running in an AT&T 630 layer, for example, where the size
- of a screen is changeable (see <B>ENVIRONMENT</B>).
-
- If the environment variable <B>TERMINFO</B> is defined, any
- program using <B>curses</B> checks for a local terminal
- definition before checking in the standard place. For
- example, if <B>TERM</B> is set to <B>att4424</B>, then the compiled
- terminal definition is found in
-
- <B>/usr/share/terminfo/a/att4424</B>.
-
- (The <B>a</B> is copied from the first letter of <B>att4424</B> to avoid
- creation of huge directories.) However, if <B>TERMINFO</B> is
- set to <B>$HOME/myterms</B>, <B>curses</B> first checks
-
- <B>$HOME/myterms/a/att4424</B>,
-
- and if that fails, it then checks
-
- <B>/usr/share/terminfo/a/att4424</B>.
-
- This is useful for developing experimental definitions or
- when write permission in <B>/usr/share/terminfo</B> is not
+ <STRONG>intrflush(stdscr,</STRONG> <STRONG>FALSE);</STRONG>
+ <STRONG>keypad(stdscr,</STRONG> <STRONG>TRUE);</STRONG>
+
+ Before a <STRONG>curses</STRONG> program is run, the tab stops of the terminal should be
+ set and its initialization strings, if defined, must be output. This
+ can be done by executing the <STRONG>tput</STRONG> <STRONG>init</STRONG> command after the shell
+ environment variable <EM>TERM</EM> has been exported. (The BSD-style <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG>
+ utility also performs this function.) See subsection "Tabs and
+ Initialization" of <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
+
+
+</PRE><H3><a name="h3-Overview">Overview</a></H3><PRE>
+ A <EM>curses</EM> library abstracts the terminal screen by representing all or
+ part of it as a <EM>WINDOW</EM> data structure. A <EM>window</EM> is a rectangular grid
+ of character cells, addressed by row and column coordinates (<EM>y</EM>, <EM>x</EM>),
+ with the upper left corner as (0, 0). A window called <STRONG>stdscr</STRONG>, the same
+ size as the terminal screen, is always available. Create others with
+ <STRONG><A HREF="curs_window.3x.html">newwin(3x)</A></STRONG>.
+
+ A <EM>curses</EM> library does not manage overlapping windows. (See <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG>
+ if you desire this.) You can either use <STRONG>stdscr</STRONG> to manage one screen-
+ filling window, or tile the screen into non-overlapping windows and not
+ use <STRONG>stdscr</STRONG> at all. Mixing the two approaches will result in
+ unpredictable, and undesired, effects.
+
+ Functions permit manipulation of a window and the <EM>cursor</EM> identifying
+ the cell within it at which the next output operation will occur.
+ Among those, the most basic are <STRONG><A HREF="curs_move.3x.html">move(3x)</A></STRONG> and <STRONG><A HREF="curs_addch.3x.html">addch(3x)</A></STRONG>: these place the
+ cursor and write a character to <STRONG>stdscr</STRONG>, respectively. As a rule,
+ window-addressing functions feature names prefixed (or infixed, see
+ below) with "w"; these allow the user to specify a pointer to a <EM>WINDOW.</EM>
+ Counterparts not thus prefixed (or infixed) affect <STRONG>stdscr</STRONG>. Because
+ moving the cursor prior to another operation is so common, <EM>curses</EM>
+ generally also provides functions with a "mv" prefix as a convenience.
+ Thus, the library defines all of <STRONG>addch</STRONG>, <STRONG>waddch</STRONG>, <STRONG>mvaddch</STRONG>, and <STRONG>mvwaddch</STRONG>.
+ When both prefixes are present, the order of arguments is a <EM>WINDOW</EM>
+ pointer first, then a <EM>y</EM> and <EM>x</EM> coordinate pair.
+
+ Updating the terminal screen with every <EM>curses</EM> call can cause
+ unpleasant flicker or inefficient use of the communications channel to
+ the device. Therefore, after using <EM>curses</EM> functions to accumulate a
+ set of desired updates that make sense to present together, call
+ <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG> to tell the library to make the user's screen look like
+ <STRONG>stdscr</STRONG>. <EM>ncurses</EM> <EM>optimizes</EM> its output by computing a minimal number of
+ operations to mutate the screen from its state at the previous refresh
+ to the new one. Effective optimization demands accurate information
+ about the terminal device: the management of such information is the
+ province of the <STRONG><A HREF="curs_terminfo.3x.html">terminfo(3x)</A></STRONG> API, a feature of every standard <EM>curses</EM>
+ implementation.
+
+ Special windows called <EM>pads</EM> may also be manipulated. These are windows
+ that are not constrained to the size of the terminal screen and whose
+ contents need not be completely displayed. See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG>.
+
+ In addition to drawing characters on the screen, rendering attributes
+ and colors may be supported, causing the characters to show up in such
+ modes as underlined, in reverse video, or in color on terminals that
+ support such display enhancements. See <STRONG><A HREF="curs_attr.3x.html">curs_attr(3x)</A></STRONG>.
+
+ <EM>curses</EM> predefines constants for a small set of line-drawing and other
+ graphics corresponding to the DEC Alternate Character Set (ACS), a
+ feature of VT100 and other terminals. See <STRONG><A HREF="curs_addch.3x.html">waddch(3x)</A></STRONG> and <STRONG><A HREF="curs_add_wch.3x.html">wadd_wch(3x)</A></STRONG>.
+
+ <EM>curses</EM> is implemented using the operating system's terminal driver;
+ keystroke events are received not as scan codes but as byte sequences.
+ Graphical keycaps (alphanumeric and punctuation keys, and the space)
+ appear as-is. Everything else, including the tab, enter/return,
+ keypad, arrow, and function keys, appears as a control character or a
+ multibyte <EM>escape</EM> <EM>sequence.</EM> <EM>curses</EM> translates these into unique <EM>key</EM>
+ <EM>codes.</EM> See <STRONG><A HREF="curs_getch.3x.html">getch(3x)</A></STRONG>.
+
+
+</PRE><H3><a name="h3-Effects-of-GUIs-and-Environment-Variables">Effects of GUIs and Environment Variables</a></H3><PRE>
+ The selection of an appropriate value of <EM>TERM</EM> in the process
+ environment is essential to correct <EM>curses</EM> and <EM>terminfo</EM> library
+ operation. A well-configured system selects a correct <EM>TERM</EM> value
+ automatically; <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG> may assist with troubleshooting exotic
+ situations.
+
+ If the environment variables <EM>LINES</EM> and <EM>COLUMNS</EM> are set, or if the
+ <EM>curses</EM> program is executing in a graphical windowing environment, the
+ information obtained thence overrides that obtained by <EM>terminfo</EM>. An
+ <EM>ncurses</EM> extension supports resizable terminals; see <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG>.
+
+ If the environment variable <EM>TERMINFO</EM> is defined, a <EM>curses</EM> program
+ checks first for a terminal type description in the location it
+ identifies. <EM>TERMINFO</EM> is useful for developing experimental type
+ descriptions or when write permission to <EM>/usr/share/terminfo</EM> is not
available.
- The integer variables <B>LINES</B> and <B>COLS</B> are defined in
- <B><curses.h></B> and will be filled in by <B>initscr</B> with the size
- of the screen. The constants <B>TRUE</B> and <B>FALSE</B> have the
- values <B>1</B> and <B>0</B>, respectively.
-
- The <B>curses</B> routines also define the <B>WINDOW</B> <B>*</B> variable
- <B>curscr</B> which is used for certain low-level operations like
- clearing and redrawing a screen containing garbage. The
- <B>curscr</B> can be used in only a few routines.
-
-
- <B>Routine</B> <B>and</B> <B>Argument</B> <B>Names</B>
- Many <B>curses</B> routines have two or more versions. The
- routines prefixed with <B>w</B> require a window argument. The
- routines prefixed with <B>p</B> require a pad argument. Those
- without a prefix generally use <B>stdscr</B>.
-
- The routines prefixed with <B>mv</B> require a <I>y</I> and <I>x</I> coordinate
- to move to before performing the appropriate action. The
- <B>mv</B> routines imply a call to <B>move</B> before the call to the
- other routine. The coordinate <I>y</I> always refers to the row
- (of the window), and <I>x</I> always refers to the column. The
- upper left-hand corner is always (0,0), not (1,1).
-
- The routines prefixed with <B>mvw</B> take both a window argument
- and <I>x</I> and <I>y</I> coordinates. The window argument is always
- specified before the coordinates.
-
- In each case, <I>win</I> is the window affected, and <I>pad</I> is the
- pad affected; <I>win</I> and <I>pad</I> are always pointers to type
- <B>WINDOW</B>.
-
- Option setting routines require a Boolean flag <I>bf</I> with the
- value <B>TRUE</B> or <B>FALSE</B>; <I>bf</I> is always of type <B>bool</B>. The
- variables <I>ch</I> and <I>attrs</I> below are always of type <B>chtype</B>.
- The types <B>WINDOW</B>, <B>SCREEN</B>, <B>bool</B>, and <B>chtype</B> are defined in
- <B><curses.h></B>. The type <B>TERMINAL</B> is defined in <B><term.h></B>.
- All other arguments are integers.

+ require a pad argument. Those without a prefix generally operate on
+ <STRONG>stdscr</STRONG>.
+
+ In function synopses, <EM>ncurses</EM> man pages apply the following names to

+ This manual page describes functions that appear in any configuration
+ of the library. There are two common configurations; see section
+ "ALTERNATE CONFIGURATIONS" below.
+
+ <EM>ncurses</EM> is the library in its "non-wide" configuration, handling only
+ eight-bit characters. It stores a character combined with
+ attributes in a <EM>chtype</EM> datum, which is often an alias of <EM>int.</EM>
+
+ Attributes alone (with no corresponding character) can be
+ stored in variables of <EM>chtype</EM> or <EM>attr</EM><STRONG>_</STRONG><EM>t</EM> type. In either
+ case, they are represented as an integral bit mask.
+
+ Each cell of a <EM>WINDOW</EM> is stored as a <EM>chtype.</EM>
+
+ <EM>ncursesw</EM> is the library in its "wide" configuration, which handles
+ character encodings requiring a larger data type than <EM>char</EM> (a
+ byte-sized type) can represent. It adds about one third more
+ calls using additional data types that can store such
+ <EM>multibyte</EM> characters.
+
+ <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM> corresponds to the non-wide configuration's <EM>chtype.</EM>
+ It always a structure type, because it stores more
+ data than fits into an integral type. A character
+ code may not be representable as a <EM>char,</EM> and
+ moreover more than one character may occupy a cell
+ (as with accent marks and other diacritics). Each
+ character is of type <EM>wchar</EM><STRONG>_</STRONG><EM>t;</EM> a complex character
+ contains one spacing character and zero or more non-
+ spacing characters (see below). Attributes and
+ color data are stored in separate fields of the
+ structure, not combined as in <EM>chtype.</EM>
+
+ Each cell of a <EM>WINDOW</EM> is stored as a <EM>cchar</EM><STRONG>_</STRONG><EM>t.</EM>
+
+ The <STRONG><A HREF="curs_getcchar.3x.html">setcchar(3x)</A></STRONG> and <STRONG><A HREF="curs_getcchar.3x.html">getcchar(3x)</A></STRONG> functions store and
+ retrieve the data from a <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM> structure. The wide library
+ API of <EM>ncurses</EM> depends on two data types standardized by ISO
+ C95.
+
+ <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM> stores a wide character. Like <EM>chtype,</EM> it may be an
+ alias of <EM>int.</EM> Depending on the character encoding,
+ a wide character may be <EM>spacing,</EM> meaning that it
+ occupies a character cell by itself and typically
+ accompanies cursor advancement, or <EM>non-spacing,</EM>
+ meaning that it occupies the same cell as a spacing
+ character, is often regarded as a "modifier" of the
+ base glyph with which it combines, and typically
+ does not advance the cursor.
+
+ <EM>wint</EM><STRONG>_</STRONG><EM>t</EM> can store a <EM>wchar</EM><STRONG>_</STRONG><EM>t</EM> or the constant <STRONG>WEOF</STRONG>,
+ analogously to the <EM>int</EM>-sized character manipulation
+ functions of ISO C and its constant <STRONG>EOF</STRONG>.
+
+ The wide library provides additional functions that
+ complement those in the non-wide library where the size of
+ the underlying character type is significant. A somewhat
+ regular naming convention relates many of the wide variants
+ to their non-wide counterparts; where a non-wide function
+ name contains "ch" or "str", prefix it with "_w" to obtain
+ the wide counterpart. For example, <STRONG>waddch</STRONG> becomes <STRONG>wadd_wch</STRONG>.
+
+ This convention is inapplicable to some non-wide function
+ names, so other transformations are used for the wide
+ configuration: in the window background management functions,
+ "bkgd" becomes "bkgrnd"; the window border-drawing and
+ -clearing functions are suffixed with "_set".

-<H2>ENVIRONMENT</H2><PRE>
- The following environment symbols are useful for
- customizing the runtime behavior of the <B>ncurses</B> library.
- The most important ones have been already discussed in
- detail.
-
- BAUDRATE
- The debugging library checks this environment symbol
- when the application has redirected output to a file.
- The symbol's numeric value is used for the baudrate.
- If no value is found <B>ncurses</B> uses 9600. This allows
- testers to construct repeatable test-cases that take
- into account costs that depend on baudrate.
-
- CC When set, change occurrences of the command_character
- (i.e., the <B>cmdch</B> capability) of the loaded terminfo
- entries to the value of this symbol. Very few
- terminfo entries provide this feature.
-
- COLUMNS
- Specify the width of the screen in characters.
- Applications running in a windowing environment
- usually are able to obtain the width of the window in
- which they are executing. If neither the $COLUMNS
- value nor the terminal's screen size is available,
- <B>ncurses</B> uses the size which may be specified in the
- terminfo database (i.e., the <B>cols</B> capability).
-
- It is important that your application use a correct
- size for the screen. However, this is not always
- possible because your application may be running on a
- host which does not honor NAWS (Negotiations About
- Window Size), or because you are temporarily running
- as another user.
-
- Either COLUMNS or LINES symbols may be specified
- independently. This is mainly useful to circumvent
- legacy misfeatures of terminal descriptions, e.g.,
- xterm which commonly specifies a 65 line screen. For
- best results, <B>lines</B> and <B>cols</B> should not be specified
- in a terminal description for terminals which are run
- as emulations.
-
- Use the <B>use_env</B> function to disable this feature.
-
- ESCDELAY
- Specifies the total time, in milliseconds, for which
- ncurses will await a character sequence, e.g., a
- function key. The default value, 1000 milliseconds,
- is enough for most uses. However, it is made a
- variable to accommodate unusual applications.
-
- The most common instance where you may wish to change
- this value is to work with slow hosts, e.g., running
- on a network. If the host cannot read characters
- rapidly enough, it will have the same effect as if
- the terminal did not send characters rapidly enough.
- The library will still see a timeout.

- Note that xterm mouse events are built up from
- character sequences received from the xterm. If your
- application makes heavy use of multiple-clicking, you
- may wish to lengthen this default value because the
- timeout applies to the composed multi-click event as
- well as the individual clicks.
-
- HOME Tells <B>ncurses</B> where your home directory is. That is
- where it may read and write auxiliary terminal
- descriptions:
-
- $HOME/.termcap
- $HOME/.terminfo
-
- LINES
- Like COLUMNS, specify the height of the screen in
- characters. See COLUMNS for a detailed description.
-
- MOUSE_BUTTONS_123
- This applies only to the OS/2 EMX port. It specifies
- the order of buttons on the mouse. OS/2 numbers a
- 3-button mouse inconsistently from other platforms:
-
- 1 = left
- 2 = right
- 3 = middle.
-
- This symbol lets you customize the mouse. The symbol
- must be three numeric digits 1-3 in any order, e.g.,
- 123 or 321. If it is not specified, <B>ncurses</B> uses
- 132.
-
- NCURSES_NO_PADDING
- Most of the terminal descriptions in the terminfo
- database are written for real "hardware" terminals.
- Many people use terminal emulators which run in a
- windowing environment and use curses-based
- applications. Terminal emulators can duplicate all
- of the important aspects of a hardware terminal, but
- they do not have the same limitations. The chief
- limitation of a hardware terminal from the standpoint
- of your application is the management of dataflow,
- i.e., timing. Unless a hardware terminal is
- interfaced into a terminal concentrator (which does
- flow control), it (or your application) must manage
- dataflow, preventing overruns. The cheapest solution
- (no hardware cost) is for your program to do this by
- pausing after operations that the terminal does
- slowly, such as clearing the display.
-
- As a result, many terminal descriptions (including
- the vt100) have delay times embedded. You may wish
- to use these descriptions, but not want to pay the
- performance penalty.
-
- Set the NCURSES_NO_PADDING symbol to disable all but
- mandatory padding. Mandatory padding is used as a
- part of special control sequences such as <I>flash</I>.
-
- NCURSES_NO_SETBUF
- Normally <B>ncurses</B> enables buffered output during
- terminal initialization. This is done (as in SVr4
- curses) for performance reasons. For testing
- purposes, both of <B>ncurses</B> and certain applications,
- this feature is made optional. Setting the
- NCURSES_NO_SETBUF variable disables output buffering,
- leaving the output in the original (usually line
- buffered) mode.
-
- NCURSES_TRACE
- During initialization, the <B>ncurses</B> debugging library
- checks the NCURSES_TRACE symbol. If it is defined,
- to a numeric value, <B>ncurses</B> calls the <B>trace</B> function,
- using that value as the argument.
-
- The argument values, which are defined in <B>curses.h</B>,
- provide several types of information. When running
- with traces enabled, your application will write the
- file <B>trace</B> to the current directory.
-
- TERM Denotes your terminal type. Each terminal type is
- distinct, though many are similar.
-
- TERMCAP
- If the <B>ncurses</B> library has been configured with
- <I>termcap</I> support, <B>ncurses</B> will check for a terminal's
- description in termcap form if it is not available in
- the terminfo database.
-
- The TERMCAP symbol contains either a terminal
- description (with newlines stripped out), or a file
- name telling where the information denoted by the
- TERM symbol exists. In either case, setting it
- directs <B>ncurses</B> to ignore the usual place for this
- information, e.g., /etc/termcap.
-
- TERMINFO
- Overrides the directory in which <B>ncurses</B> searches for
- your terminal description. This is the simplest, but
- not the only way to change the list of directories.
- The complete list of directories in order follows:
-
- - the last directory to which <B>ncurses</B> wrote, if any,
- is searched first.
-
- - the directory specified by the TERMINFO symbol
-
- - $HOME/.terminfo
-
- - directories listed in the TERMINFO_DIRS symbol
-
- - one or more directories whose names are configured
- and compiled into the ncurses library, e.g.,
- /usr/share/terminfo
-
- TERMINFO_DIRS
- Specifies a list of directories to search for
- terminal descriptions. The list is separated by
- colons (i.e., ":"). All of the terminal descriptions
- are in terminfo form, which makes a subdirectory
- named for the first letter of the terminal names
- therein.
-
- TERMPATH
- If TERMCAP does not hold a file name then <B>ncurses</B>
- checks the TERMPATH symbol. This is a list of
- filenames separated by colons (i.e., ":"). If the
- TERMPATH symbol is not set, <B>ncurses</B> looks in the
- files /etc/termcap, /usr/share/misc/termcap and
- $HOME/.termcap, in that order.
-
- The library may be configured to disregard the following
- variables when the current user is the superuser (root),
- or if the application uses setuid or setgid permissions:
- $TERMINFO, $TERMINFO_DIRS, $TERMPATH, as well as $HOME.

- The <B>ncurses</B> library can be compiled with an option
- (<B>-DUSE_GETCAP</B>) that falls back to the old-style
- /etc/termcap file if the terminal setup code cannot find a
- terminfo entry corresponding to <B>TERM</B>. Use of this feature
- is not recommended, as it essentially includes an entire
- termcap compiler in the <B>ncurses</B> startup code, at
- significant cost in core and startup cycles.
-
- The <B>ncurses</B> library includes facilities for capturing
- mouse events on certain terminals (including xterm). See
- the <B><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></B> manual page for details.

- details. In addition, the library may be configured with
- a SIGWINCH handler.
-
- The <B>ncurses</B> library extends the fixed set of function key
- capabilities of terminals by allowing the application
- designer to define additional key sequences at runtime.

- details.
-
- The <B>ncurses</B> library can exploit the capabilities of
- terminals which implement the ISO-6429 SGR 39 and SGR 49
- controls, which allow an application to reset the terminal
- to its original foreground and background colors. From
- the users' perspective, the application is able to draw
- colored text on a background whose color is set
- independently, providing better control over color
- contrasts. See the <B><A HREF="use_default_colors.3x.html">use_default_colors(3x)</A></B> manual page for

+ Most of the terminal descriptions in the terminfo database are written
+ for real "hardware" terminals. Many people use terminal emulators
+ which run in a windowing environment and use curses-based applications.
+ Terminal emulators can duplicate all of the important aspects of a
+ hardware terminal, but they do not have the same limitations. The
+ chief limitation of a hardware terminal from the standpoint of your
+ application is the management of dataflow, i.e., timing. Unless a
+ hardware terminal is interfaced into a terminal concentrator (which
+ does flow control), it (or your application) must manage dataflow,
+ preventing overruns. The cheapest solution (no hardware cost) is for
+ your program to do this by pausing after operations that the terminal
+ does slowly, such as clearing the display.

+
+ <EM>ncurses</EM> enabled buffered output during terminal initialization. This

+
+ In the current implementation, <EM>ncurses</EM> performs its own buffering and

+ <EM>ncurses</EM> can be configured to read from multiple terminal databases.

+
+ <STRONG>o</STRONG> Normally these are stored in a directory tree, using subdirectories
+ named by the first letter of the terminal names therein.
+
+ This is the scheme used in System V, which legacy Unix systems use,
+ and the <EM>TERMINFO</EM> variable is used by <EM>curses</EM> applications on those
+ systems to override the default location of the terminal database.
+
+ <STRONG>o</STRONG> If <EM>ncurses</EM> is built to use hashed databases, then each entry in
+ this list may be the path of a hashed database file, e.g.,
+
+ /usr/share/terminfo.db
+
+ rather than
+
+ /usr/share/terminfo/
+
+ The hashed database uses less disk-space and is a little faster
+ than the directory tree. However, some applications assume the
+ existence of the directory tree, reading it directly rather than
+ using the terminfo library calls.
+
+ <STRONG>o</STRONG> If <EM>ncurses</EM> is built with a support for reading termcap files
+ directly, then an entry in this list may be the path of a termcap
+ file.
+
+ <STRONG>o</STRONG> If the <EM>TERMINFO</EM> variable begins with "hex:" or "b64:", <EM>ncurses</EM> uses

+ the script with the <STRONG>--help</STRONG> option to peruse them all. A few are of
+ particular significance to the application developer employing <EM>ncurses.</EM>
+
+ --disable-overwrite
+ The standard include for <EM>ncurses</EM> is as noted in <STRONG>SYNOPSIS</STRONG>:
+
+ <STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
+
+ This option is used to avoid filename conflicts when <EM>ncurses</EM> is
+ not the main implementation of curses of the computer. If <EM>ncurses</EM>
+ is installed disabling overwrite, it puts its headers in a
+ subdirectory, e.g.,
+
+ <STRONG>#include</STRONG> <STRONG><ncurses/curses.h></STRONG>
+
+ It also omits a symbolic link which would allow you to use
+ <STRONG>-lcurses</STRONG> to build executables.
+
+ --enable-widec
+ The configure script renames the library and (if the
+ <STRONG>--disable-overwrite</STRONG> option is used) puts the header files in a
+ different subdirectory. All of the library names have a "w"
+ appended to them, i.e., instead of
+
+ <STRONG>-lncurses</STRONG>
+
+ you link with
+
+ <STRONG>-lncursesw</STRONG>
+
+ You must also enable the wide-character features in the header
+ file when compiling for the wide-character library to use the
+ extended (wide-character) functions. The symbol which enables
+ these features has changed since XSI Curses, Issue 4:
+
+ <STRONG>o</STRONG> Originally, the wide-character feature required the symbol
+ <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG> but that was only valid for XPG4
+ (1996).
+
+ <STRONG>o</STRONG> Later, that was deemed conflicting with <STRONG>_XOPEN_SOURCE</STRONG> defined
+ to 500.
+
+ <STRONG>o</STRONG> As of mid-2018, none of the features in this implementation
+ require a <STRONG>_XOPEN_SOURCE</STRONG> feature greater than 600. However,
+ X/Open Curses, Issue 7 (2009) recommends defining it to 700.
+
+ <STRONG>o</STRONG> Alternatively, you can enable the feature by defining
+ <STRONG>NCURSES_WIDECHAR</STRONG> with the caveat that some other header file
+ than <STRONG>curses.h</STRONG> may require a specific value for <STRONG>_XOPEN_SOURCE</STRONG>
+ (or a system-specific symbol).
+
+ The <EM>curses.h</EM> header file installed for the wide-character library
+ is designed to be compatible with the non-wide library's header.
+ Only the size of the <EM>WINDOW</EM> structure differs; few applications
+ require more than pointers to <EM>WINDOW</EM>s.
+
+ If the headers are installed allowing overwrite, the wide-
+ character library's headers should be installed last, to allow
+ applications to be built using either library from the same set of
+ headers.
+
+ --with-pthread
+ The configure script renames the library. All of the library
+ names have a "t" appended to them (before any "w" added by
+ <STRONG>--enable-widec</STRONG>).
+
+ The global variables such as <STRONG>LINES</STRONG> are replaced by macros to allow
+ read-only access. At the same time, setter-functions are provided
+ to set these values. Some applications (very few) may require
+ changes to work with this convention.
+
+ --with-shared
+
+ --with-normal
+
+ --with-debug
+
+ --with-profile
+ The shared and normal (static) library names differ by their
+ suffixes, e.g., <STRONG>libncurses.so</STRONG> and <STRONG>libncurses.a</STRONG>. The debug and
+ profiling libraries add a "_g" and a "_p" to the root names
+ respectively, e.g., <STRONG>libncurses_g.a</STRONG> and <STRONG>libncurses_p.a</STRONG>.
+
+ --with-termlib
+ Low-level functions which do not depend upon whether the library
+ supports wide-characters, are provided in the tinfo library.
+
+ By doing this, it is possible to share the tinfo library between
+ wide/normal configurations as well as reduce the size of the
+ library when only low-level functions are needed.
+

+ <EM>ncurses</EM> allows an application to query the terminal for the presence of
+ a wide variety of special keys; see <STRONG><A HREF="curs_getch.3x.html">has_key(3x)</A></STRONG>.
+
+ <EM>ncurses</EM> extends the fixed set of function key capabilities specified by

+ <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG>, and <STRONG><A HREF="keyok.3x.html">keyok(3x)</A></STRONG>.
+
+ <EM>ncurses</EM> can exploit the capabilities of terminals implementing
+ ISO 6429/ECMA-48 SGR 39 and SGR 49 sequences, which allow an
+ application to reset the terminal to its original foreground and
+ background colors. From a user's perspective, the application is able
+ to draw colored text on a background whose color is set independently,
+ providing better control over color contrasts. See <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG>.
+
+ An <EM>ncurses</EM> application can choose to hide the internal details of
+ <EM>WINDOW</EM> structures, instead using accessor functions such as
+ <STRONG><A HREF="curs_opaque.3x.html">is_scrollok(3x)</A></STRONG>.

+ that can gather color information from them when many colors are

+
+ Some extensions are only available if <EM>ncurses</EM> is compiled to support

+ <EM>info</EM> entry corresponding to <EM>TERM.</EM> Use of this feature is not
+ recommended, as it essentially includes an entire <EM>termcap</EM> compiler
+ in the <EM>ncurses</EM> startup code, at a cost in memory usage and
+ application launch latency.
+
+ <EM>PDCurses</EM> and NetBSD <EM>curses</EM> incorporate some <EM>ncurses</EM> extensions.
+ Individual man pages indicate where this is the case.

+ X/Open Curses defines two levels of conformance, "base" and "enhanced".
+ The latter includes several additional features, such as wide-character
+ and color support. <EM>ncurses</EM> intends base-level conformance with X/Open
+ Curses, and supports nearly all its enhanced features.
+
+ Differences between X/Open Curses and <EM>ncurses</EM> are documented in the
+ "PORTABILITY" sections of applicable man pages.
+
+
+</PRE><H3><a name="h3-Error-Checking">Error Checking</a></H3><PRE>
+ In many cases, X/Open Curses is vague about error conditions, omitting
+ some of the SVr4 documentation.
+
+ Unlike other implementations, this one checks parameters such as
+ pointers to <EM>WINDOW</EM> structures to ensure they are not null. The main
+ reason for providing this behavior is to guard against programmer
+ error. The standard interface does not provide a way for the library
+ to tell an application which of several possible errors were detected.
+ Relying on this (or some other) extension will adversely affect the
+ portability of curses applications.
+
+
+</PRE><H3><a name="h3-Padding-Differences">Padding Differences</a></H3><PRE>
+ In historic curses versions, delays embedded in the capabilities <STRONG>cr</STRONG>,
+ <STRONG>ind</STRONG>, <STRONG>cub1</STRONG>, <STRONG>ff</STRONG> and <STRONG>tab</STRONG> activated corresponding delay bits in the Unix
+ tty driver. In this implementation, all padding is done by sending NUL
+ bytes. This method is slightly more expensive, but narrows the
+ interface to the Unix kernel significantly and increases the package's
+ portability correspondingly.
+
+
+</PRE><H3><a name="h3-Header-Files">Header Files</a></H3><PRE>
+ The header file <EM>curses.h</EM> itself includes the header files <EM>stdio.h</EM> and
+ <EM>unctrl.h</EM>.
+
+ X/Open Curses has more to say, but does not finish the story:
+
+ The inclusion of <curses.h> may make visible all symbols from the
+ headers <stdio.h>, <term.h>, <termios.h>, and <wchar.h>.
+
+ Here is a more complete story:
+
+ <STRONG>o</STRONG> Starting with BSD curses, all implementations have included
+ <stdio.h>.
+
+ BSD curses included <curses.h> and <unctrl.h> from an internal
+ header file <EM>curses.ext</EM> ("ext" abbreviated "externs").
+
+ BSD curses used <stdio.h> internally (for <STRONG>printw</STRONG> and <STRONG>scanw</STRONG>), but
+ nothing in <curses.h> itself relied upon <stdio.h>.
+
+ <STRONG>o</STRONG> SVr2 curses added <STRONG><A HREF="curs_initscr.3x.html">newterm(3x)</A></STRONG>, which relies upon <stdio.h>. That
+ is, the function prototype uses <STRONG>FILE</STRONG>.
+
+ SVr4 curses added <STRONG>putwin</STRONG> and <STRONG>getwin</STRONG>, which also use <stdio.h>.
+
+ X/Open Curses documents all three of these functions.
+
+ SVr4 curses and X/Open Curses do not require the developer to
+ include <stdio.h> before including <curses.h>. Both document
+ curses showing <curses.h> as the only required header.
+
+ As a result, standard <curses.h> will always include <stdio.h>.
+
+ <STRONG>o</STRONG> X/Open Curses is inconsistent with respect to SVr4 regarding
+ <unctrl.h>.
+
+ As noted in <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG>, <EM>ncurses</EM> includes <unctrl.h> from
+ <curses.h> (like SVr4).
+
+ <STRONG>o</STRONG> X/Open's comments about <term.h> and <termios.h> may refer to HP-UX
+ and AIX:
+ HP-UX curses includes <term.h> from <curses.h> to declare <STRONG>setupterm</STRONG>
+ in curses.h, but <EM>ncurses</EM> (and Solaris curses) do not.
+ AIX curses includes <term.h> and <termios.h>. Again, <EM>ncurses</EM> (and
+ Solaris curses) do not.
+ <STRONG>o</STRONG> X/Open says that <curses.h> <EM>may</EM> include <term.h>, but there is no
+ requirement that it do that.
+ Some programs use functions declared in both <curses.h> and
+ <term.h>, and must include both headers in the same module. Very
+ old versions of AIX curses required including <curses.h> before
+ including <term.h>.
+ Because <EM>ncurses</EM> header files include the headers needed to define
+ datatypes used in the headers, <EM>ncurses</EM> header files can be included
+ in any order. But for portability, you should include <curses.h>
+ before <term.h>.
+ <STRONG>o</STRONG> X/Open Curses says <EM>"may</EM> <EM>make</EM> <EM>visible"</EM> because including a header
+ file does not necessarily make all symbols in it visible (there are
+ ifdef's to consider).
+ For instance, in <EM>ncurses</EM> <wchar.h> <EM>may</EM> be included if the proper
+ symbol is defined, and if <EM>ncurses</EM> is configured for wide-character
+ support. If the header is included, its symbols may be made
+ visible. That depends on the value used for <STRONG>_XOPEN_SOURCE</STRONG> feature
+ test macro.
+ <STRONG>o</STRONG> X/Open Curses documents one required header, in a special case:
+ <stdarg.h> before <curses.h> to prototype the <STRONG>vw_printw</STRONG> and
+ <STRONG>vw_scanw</STRONG> functions (as well as the obsolete the <STRONG>vwprintw</STRONG> and
+ <STRONG>vwscanw</STRONG> functions). Each of those uses a <STRONG>va_list</STRONG> parameter.
+ The two obsolete functions were introduced in SVr3. The other
+ functions were introduced in X/Open Curses. In between, SVr4
+ curses provided for the possibility that an application might
+ include either <varargs.h> or <stdarg.h>. Initially, that was done
+ by using <STRONG>void*</STRONG> for the <STRONG>va_list</STRONG> parameter. Later, a special type
+ (defined in <stdio.h>) was introduced, to allow for compiler type-
+ checking. That special type is always available, because <stdio.h>
+ is always included by <curses.h>.
+ None of the X/Open Curses implementations require an application to
+ include <stdarg.h> before <curses.h> because they either have
+ allowed for a special type, or (like <EM>ncurses</EM>) include <stdarg.h>
+ directly to provide a portable interface.
