</PRE><H2><a name="h2-SYNOPSIS">SYNOPSIS</a></H2><PRE>
</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
- The <STRONG>ncurses</STRONG> library routines give the user a terminal-
- independent method of updating character screens with rea-
- sonable optimization. This implementation is "new curses"
- (ncurses) and is the approved replacement for 4.4BSD clas-
- sic curses, which has been discontinued. This describes
- <STRONG>ncurses</STRONG> version 6.0 (patch 20161022).
-
- The <STRONG>ncurses</STRONG> library emulates the curses library of System
- V Release 4 UNIX, and XPG4 (X/Open Portability Guide)
- curses (also known as XSI curses). XSI stands for X/Open
- System Interfaces Extension. The <STRONG>ncurses</STRONG> library is
- freely redistributable in source form. Differences from
- the SVr4 curses are summarized under the <STRONG>EXTENSIONS</STRONG> and
- <STRONG>PORTABILITY</STRONG> sections below and described in detail in the
- respective <STRONG>EXTENSIONS</STRONG>, <STRONG>PORTABILITY</STRONG> and <STRONG>BUGS</STRONG> sections of
- individual man pages.
-
- The <STRONG>ncurses</STRONG> library also provides many useful extensions,
- i.e., features which cannot be implemented by a simple
- add-on library but which require access to the internals
- of the library.
-
- 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 direc-
- tory) that describe curses actions. See also the section
- on <STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</STRONG>.
-
- The <STRONG>ncurses</STRONG> package supports: overall screen, window and
- pad manipulation; output to windows and pads; reading ter-
- minal input; control over terminal and <STRONG>curses</STRONG> input and
- output options; environment query routines; color manipu-
- lation; use of soft label keys; terminfo capabilities; and
- access to low-level terminal-manipulation routines.
+ The "new curses" library offers the programmer a terminal-independent
+ means of reading keyboard and mouse input and updating character-cell
+ terminals with output optimized to minimize screen updates. <EM>ncurses</EM>
+ replaces the <EM>curses</EM> libraries from System V Release 4 Unix ("SVr4") and
+ 4.4BSD Unix, the development of which ceased in the 1990s. This
+ document describes <EM>ncurses</EM> version 6.4 (patch 20240420).
+
+ <EM>ncurses</EM> permits control of the terminal screen's contents; abstraction
+ and subdivision thereof with <EM>windows</EM> and <EM>pads</EM>; the reading of terminal
+ input; control of terminal input and output options; environment query
+ routines; color manipulation; the definition and use of <EM>soft</EM> <EM>label</EM>
+ keys; <EM>terminfo</EM> capability access; a <EM>termcap</EM> compatibility interface;
+ and an abstraction of the system's API for manipulating the terminal
+ (such as <STRONG>termios(3)</STRONG>).
+
+ <EM>ncurses</EM> implements the standard interface described by X/Open Curses
+ Issue 7. In many behavioral details not standardized by X/Open,
+ <EM>ncurses</EM> emulates the <EM>curses</EM> library of SVr4 and provides numerous
+ useful extensions.
+
+ <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 issues 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 for
+ 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 <EM>curses</EM> application must be linked with the library; use the <STRONG>-lncurses</STRONG>
+ option to your compiler or linker. A debugging version of the library
+ may be available; if so, link with it using <STRONG>-lncurses_g</STRONG>. (Your system
+ integrator may have installed these libraries such that you can use the
+ options <STRONG>-lcurses</STRONG> and <STRONG>-lcurses_g</STRONG>, respectively.) The <EM>ncurses</EM><STRONG>_</STRONG><EM>g</EM> library
+ generates trace logs (in a file called <EM>trace</EM> in the current directory)
+ that describe <EM>ncurses</EM> actions. See section "ALTERNATE CONFIGURATIONS"
+ below.
+
+
+</PRE><H3><a name="h3-Application-Structure">Application Structure</a></H3><PRE>
+ A <EM>curses</EM> application uses information from the system locale;
+ <STRONG>setlocale(3)</STRONG> prepares it for <EM>curses</EM> library calls.
+
+ setlocale(LC_ALL, "");
+
+ If the locale is not thus initialized, the library assumes that
+ characters are printable as in ISO 8859-1, to work with certain legacy
+ programs. You should initialize the locale; do not expect consistent
+ behavior from the library when the locale has not been set up.
+
+ <STRONG><A HREF="curs_initscr.3x.html">initscr(3x)</A></STRONG> or <STRONG><A HREF="curs_initscr.3x.html">newterm(3x)</A></STRONG> must be called to initialize <EM>curses</EM> before
+ use of any functions that deal with windows and screens.
+
+ To get character-at-a-time input without echoing--most interactive,
+ screen-oriented programs want this--use the following sequence.
+
+ initscr(); cbreak(); noecho();
+
+ Most applications perform further setup as follows.
+
+ intrflush(stdscr, FALSE);
+ keypad(stdscr, TRUE);
+
+ A <EM>curses</EM> program then often enters an event loop of some sort. Call
+ <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG> before exiting.
+
+
+</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 (but see below).
+ 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.
+
+ Frequent changes to the terminal screen can cause unpleasant flicker or
+ inefficient use of the communication channel to the device, so the
+ library does not generally update it automatically. 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>. The library <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 forms-drawing 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>.
+
+ <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>.
+
+ <EM>ncurses</EM> provides reimplementations of the SVr4 <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG>, <STRONG><A HREF="form.3x.html">form(3x)</A></STRONG>, and
+ <STRONG><A HREF="menu.3x.html">menu(3x)</A></STRONG> libraries to ease construction of user interfaces with <EM>curses</EM>.
</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</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 setup.
-
- The function <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG> must be called to initial-
- ize the library before any of the other routines that deal
- with windows and screens are used. The routine <STRONG>endwin</STRONG>
- must be called before exiting.
-
- To get character-at-a-time input without echoing (most
- interactive, screen oriented programs want this), the fol-
- lowing sequence should be used:
-
- <STRONG>initscr();</STRONG> <STRONG>cbreak();</STRONG> <STRONG>noecho();</STRONG>
-
- Most programs would additionally use the sequence:
-
- <STRONG>nonl();</STRONG>
- <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 ter-
- minal 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
- <STRONG>TERM</STRONG> has been exported. <STRONG>tset(1)</STRONG> is usually responsible
- for doing this. [See <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> for further details.]
-
-
-</PRE><H3><a name="h3-Datatypes">Datatypes</a></H3><PRE>
- The <STRONG>ncurses</STRONG> library permits manipulation of data struc-
- tures, called <EM>windows</EM>, which can be thought of as two-
- dimensional arrays of characters representing all or part
- of a CRT screen. A default window called <STRONG>stdscr</STRONG>, which is
- the size of the terminal screen, is supplied. Others may
- be created with <STRONG>newwin</STRONG>.
-
- Note that <STRONG>curses</STRONG> does not handle overlapping windows,
- that's done by the <STRONG><A HREF="panel.3x.html">panel(3x)</A></STRONG> library. This means that you
- can either use <STRONG>stdscr</STRONG> or divide the screen into tiled win-
- dows and not using <STRONG>stdscr</STRONG> at all. Mixing the two will
- result in unpredictable, and undesired, effects.
-
- Windows are referred to by variables declared as <STRONG>WINDOW</STRONG> <STRONG>*</STRONG>.
- These data structures are manipulated with routines
- described here and elsewhere in the <STRONG>ncurses</STRONG> manual pages.
- Among those, the most basic routines are <STRONG>move</STRONG> and <STRONG>addch</STRONG>.
- More general versions of these routines are included with
- names beginning with <STRONG>w</STRONG>, allowing the user to specify a
- window. The routines not beginning with <STRONG>w</STRONG> affect <STRONG>stdscr</STRONG>.
-
- After using routines to manipulate a window, <STRONG>refresh</STRONG> is
- called, telling <STRONG>curses</STRONG> to make the user's CRT screen look
- like <STRONG>stdscr</STRONG>. The characters in a window are actually of
- type <STRONG>chtype</STRONG>, (character and attribute data) so that other
- information about the character may also be stored with
- each character.
-
- Special windows called <EM>pads</EM> may also be manipulated.
- These are windows which are not constrained to the size of
- the screen and whose contents need not be completely dis-
- played. See <STRONG><A HREF="curs_pad.3x.html">curs_pad(3x)</A></STRONG> for more information.
-
- In addition to drawing characters on the screen, video
- attributes and colors may be supported, causing the char-
- acters 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, <STRONG>curses</STRONG> 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
- <STRONG><curses.h></STRONG>, such as <STRONG>A_REVERSE</STRONG>, <STRONG>ACS_HLINE</STRONG>, and <STRONG>KEY_LEFT</STRONG>.
-
-
-</PRE><H3><a name="h3-Environment-variables">Environment variables</a></H3><PRE>
- If the environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> are set, or
- if the program is executing in a window environment, line
- and column information in the environment will override
- information read by <EM>terminfo</EM>. This would affect a program
- running in an AT&T 630 layer, for example, where the size
- of a screen is changeable (see <STRONG>ENVIRONMENT</STRONG>).
-
- If the environment variable <STRONG>TERMINFO</STRONG> is defined, any pro-
- gram using <STRONG>curses</STRONG> checks for a local terminal definition
- before checking in the standard place. For example, if
- <STRONG>TERM</STRONG> is set to <STRONG>att4424</STRONG>, then the compiled terminal defini-
- tion is found in
-
- <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
-
- (The <STRONG>a</STRONG> is copied from the first letter of <STRONG>att4424</STRONG> to avoid
- creation of huge directories.) However, if <STRONG>TERMINFO</STRONG> is
- set to <STRONG>$HOME/myterms</STRONG>, <STRONG>curses</STRONG> first checks
-
- <STRONG>$HOME/myterms/a/att4424</STRONG>,
-
- and if that fails, it then checks
-
- <STRONG>/usr/share/terminfo/a/att4424</STRONG>.
-
- This is useful for developing experimental definitions or
- when write permission in <STRONG>/usr/share/terminfo</STRONG> is not avail-
- able.
-
- The integer variables <STRONG>LINES</STRONG> and <STRONG>COLS</STRONG> are defined in
- <STRONG><curses.h></STRONG> and will be filled in by <STRONG>initscr</STRONG> with the size
- of the screen. The constants <STRONG>TRUE</STRONG> and <STRONG>FALSE</STRONG> have the val-
- ues <STRONG>1</STRONG> and <STRONG>0</STRONG>, respectively.
-
- The <STRONG>curses</STRONG> routines also define the <STRONG>WINDOW</STRONG> <STRONG>*</STRONG> variable
- <STRONG>curscr</STRONG> which is used for certain low-level operations like
- clearing and redrawing a screen containing garbage. The
- <STRONG>curscr</STRONG> can be used in only a few routines.
-
-
-</PRE><H3><a name="h3-Routine-and-Argument-Names">Routine and Argument Names</a></H3><PRE>
- Many <STRONG>curses</STRONG> routines have two or more versions. The rou-
- tines prefixed with <STRONG>w</STRONG> require a window argument. The rou-
- tines prefixed with <STRONG>p</STRONG> require a pad argument. Those with-
- out a prefix generally use <STRONG>stdscr</STRONG>.
-
- The routines prefixed with <STRONG>mv</STRONG> require a <EM>y</EM> and <EM>x</EM> coordinate
- to move to before performing the appropriate action. The
- <STRONG>mv</STRONG> routines imply a call to <STRONG>move</STRONG> before the call to the
- other routine. The coordinate <EM>y</EM> always refers to the row
- (of the window), and <EM>x</EM> always refers to the column. The
- upper left-hand corner is always (0,0), not (1,1).
-
- The routines prefixed with <STRONG>mvw</STRONG> take both a window argument
- and <EM>x</EM> and <EM>y</EM> coordinates. The window argument is always
- specified before the coordinates.
-
- In each case, <EM>win</EM> is the window affected, and <EM>pad</EM> is the
- pad affected; <EM>win</EM> and <EM>pad</EM> are always pointers to type <STRONG>WIN-</STRONG>
- <STRONG>DOW</STRONG>.
-
- Option setting routines require a Boolean flag <EM>bf</EM> with the
- value <STRONG>TRUE</STRONG> or <STRONG>FALSE</STRONG>; <EM>bf</EM> is always of type <STRONG>bool</STRONG>. Most of
- the data types used in the library routines, such as <STRONG>WIN-</STRONG>
- <STRONG>DOW</STRONG>, <STRONG>SCREEN</STRONG>, <STRONG>bool</STRONG>, and <STRONG>chtype</STRONG> are defined in <STRONG><curses.h></STRONG>.
- Types used for the terminfo routines such as <STRONG>TERMINAL</STRONG> are
- defined in <STRONG><term.h></STRONG>.
-
- This manual page describes functions which may appear in
- any configuration of the library. There are two common
- configurations of the library:
-
- <EM>ncurses</EM>
- the "normal" library, which handles 8-bit charac-
- ters. The normal (8-bit) library stores charac-
- ters combined with attributes in <STRONG>chtype</STRONG> data.
-
- Attributes alone (no corresponding character) may
- be stored in <STRONG>chtype</STRONG> or the equivalent <STRONG>attr_t</STRONG> data.
- In either case, the data is stored in something
- like an integer.
-
- Each cell (row and column) in a <STRONG>WINDOW</STRONG> is stored
- as a <STRONG>chtype</STRONG>.
-
- <EM>ncursesw</EM>
- the so-called "wide" library, which handles multi-
- byte characters (see the section on <STRONG>ALTERNATE</STRONG> <STRONG>CON-</STRONG>
- <STRONG>FIGURATIONS</STRONG>). The "wide" library includes all of
- the calls from the "normal" library. It adds
- about one third more calls using data types which
- store multibyte characters:
-
- <STRONG>cchar_t</STRONG>
- corresponds to <STRONG>chtype</STRONG>. However it is a
- structure, because more data is stored than
- can fit into an integer. The characters are
- large enough to require a full integer value
- - and there may be more than one character
- per cell. The video attributes and color are
- stored in separate fields of the structure.
-
- Each cell (row and column) in a <STRONG>WINDOW</STRONG> is
- stored as a <STRONG>cchar_t</STRONG>.
-
- <STRONG>wchar_t</STRONG>
- stores a "wide" character. Like <STRONG>chtype</STRONG>, this
- may be an integer.
-
- <STRONG>wint_t</STRONG>
- stores a <STRONG>wchar_t</STRONG> or <STRONG>WEOF</STRONG> - not the same,
- though both may have the same size.
-
- The "wide" library provides new functions which
- are analogous to functions in the "normal"
- library. There is a naming convention which
- relates many of the normal/wide variants: a "_w"
- is inserted into the name. For example, <STRONG>waddch</STRONG>
- becomes <STRONG>wadd_wch</STRONG>.

+ 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 you change the terminal type, export the <EM>TERM</EM> environment variable
+ in the shell, then run <STRONG><A HREF="tset.1.html">tset(1)</A></STRONG> or the "<STRONG>tput</STRONG> <STRONG>init</STRONG>" command. See
+ subsection "Tabs and Initialization" of <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
+
+ 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.
+
+ See section "ENVIRONMENT" below.
+
+
+</PRE><H3><a name="h3-Naming-Conventions">Naming Conventions</a></H3><PRE>
+ <EM>curses</EM> offers many functions in variant forms using a regular set of
+ alternatives to the name of an elemental one. Those prefixed with "w"
+ require a <EM>WINDOW</EM> pointer argument; those with a "mv" prefix first
+ perform cursor movement using <STRONG><A HREF="curs_move.3x.html">wmove(3x)</A></STRONG>; a "mvw" prefix indicates both.
+ The "w" function is typically the elemental one; the removal of this
+ prefix usually indicates operation on <STRONG>stdscr</STRONG>.
+
+ Four functions prefixed with "p" require a pad argument.
+
+ 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 fit into a standard scalar 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>.
+
+ <STRONG><A HREF="curs_getcchar.3x.html">setcchar(3x)</A></STRONG> and <STRONG><A HREF="curs_getcchar.3x.html">getcchar(3x)</A></STRONG> store and retrieve <EM>cchar</EM><STRONG>_</STRONG><EM>t</EM>
+ data. 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>,

+ <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>.
+ (Exceptions that add only "w" comprise <STRONG>addwstr</STRONG>, <STRONG>inwstr</STRONG>, and
+ their variants.)
+
+ This convention is inapplicable to some non-wide function
+ names, so other transformations are used for the wide
+ configuration: the window background management function
+ "bkgd" becomes "bkgrnd"; the window border-drawing and
+ -clearing functions are suffixed with "_set"; and character
+ attribute manipulation functions like "attron" become
+ "attr_on".

- When set, change occurrences of the command_character
- (i.e., the <STRONG>cmdch</STRONG> capability) of the loaded terminfo
- entries to the value of this variable. Very few terminfo

-</PRE><H3><a name="h3-BAUDRATE">BAUDRATE</a></H3><PRE>
- The debugging library checks this environment variable
- when the application has redirected output to a file. The
- variable's numeric value is used for the baudrate. If no
- value is found, <STRONG>ncurses</STRONG> uses 9600. This allows testers to
- construct repeatable test-cases that take into account
- costs that depend on baudrate.
-
-
-</PRE><H3><a name="h3-COLUMNS">COLUMNS</a></H3><PRE>
- Specify the width of the screen in characters. Applica-
- tions running in a windowing environment usually are able
- to obtain the width of the window in which they are exe-
- cuting. If neither the <STRONG>COLUMNS</STRONG> value nor the terminal's
- screen size is available, <STRONG>ncurses</STRONG> uses the size which may
- be specified in the terminfo database (i.e., the <STRONG>cols</STRONG>
- capability).
-
- It is important that your application use a correct size
- for the screen. 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. However, setting
- <STRONG>COLUMNS</STRONG> and/or <STRONG>LINES</STRONG> overrides the library's use of the
- screen size obtained from the operating system.
-
- Either <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> symbols may be specified indepen-
- dently. This is mainly useful to circumvent legacy mis-
- features of terminal descriptions, e.g., xterm which com-
- monly specifies a 65 line screen. For best results, <STRONG>lines</STRONG>
- and <STRONG>cols</STRONG> should not be specified in a terminal description
- for terminals which are run as emulations.
-
- Use the <STRONG>use_env</STRONG> function to disable all use of external
- environment (but not including system calls) to determine
- the screen size. Use the <STRONG>use_tioctl</STRONG> function to update
- <STRONG>COLUMNS</STRONG> or <STRONG>LINES</STRONG> to match the screen size obtained from

- 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 net-
- work. 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.
-
- In addition to the environment variable, this implementa-
- tion provides a global variable with the same name. Por-

- 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 environ-
- ment and use curses-based applications. Terminal emula-
- tors can duplicate all of the important aspects of a hard-
- ware 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.

-
- <STRONG>ncurses</STRONG> enabled buffered output during terminal initial-

- Setting the NCURSES_NO_SETBUF variable disabled output
- buffering, leaving the output in the original (usually
- line buffered) mode.
-
- In the current implementation, ncurses performs its own
- buffering and does not require this workaround. It does
- not modify the buffering of the standard output.
-
- The reason for the change was to make the behavior for
- interrupts and other signals more robust. One drawback is
- that certain nonconventional programs would mix ordinary
- stdio calls with ncurses calls and (usually) work. This
- is no longer possible since ncurses is not using the
- buffered standard output but its own output (to the same
- file descriptor). As a special case, the low-level calls

- During initialization, the <STRONG>ncurses</STRONG> library checks for spe-
- cial cases where VT100 line-drawing (and the corresponding
- alternate character set capabilities) described in the
- terminfo are known to be missing. Specifically, when run-
- ning in a UTF-8 locale, the Linux console emulator and the
- GNU screen program ignore these. Ncurses checks the TERM
- environment variable for these. For other special cases,
- you should set this environment variable. Doing this
- tells ncurses to use Unicode values which correspond to
- the VT100 line-drawing glyphs. That works for the special
- cases cited, and is likely to work for terminal emulators.
-
- When setting this variable, you should set it to a nonzero
- value. Setting it to zero (or to a nonnumber) disables

+
+ <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).

+ is designed to be compatible with the non-wide library's header.

+ <EM>PDCurses</EM> and NetBSD <EM>curses</EM> incorporate some <EM>ncurses</EM> extensions.
+ Individual man pages indicate where this is the case.
</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
- The <STRONG>ncurses</STRONG> library is intended to be BASE-level confor-
- mant with XSI Curses. The EXTENDED XSI Curses functional-
- ity (including color support) is supported.
-
- A small number of local differences (that is, individual
- differences between the XSI Curses and <STRONG>ncurses</STRONG> calls) are
- described in <STRONG>PORTABILITY</STRONG> sections of the library man
- pages.
-
- Unlike other implementations, this one checks parameters
- such as pointers to WINDOW 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 applica-
- tion which of several possible errors were detected.
- Relying on this (or some other) extension will adversely
- affect the portability of curses applications.
-
- This implementation also contains several extensions:
-
- <STRONG>o</STRONG> The routine <STRONG>has_key</STRONG> is not part of XPG4, nor is it
- present in SVr4. See the <STRONG><A HREF="curs_getch.3x.html">curs_getch(3x)</A></STRONG> manual page
- for details.
-
- <STRONG>o</STRONG> The routine <STRONG>slk_attr</STRONG> is not part of XPG4, nor is it
- present in SVr4. See the <STRONG><A HREF="curs_slk.3x.html">curs_slk(3x)</A></STRONG> manual page for
- details.
-
- <STRONG>o</STRONG> The routines <STRONG>getmouse</STRONG>, <STRONG>mousemask</STRONG>, <STRONG>ungetmouse</STRONG>, <STRONG>mousein-</STRONG>
- <STRONG>terval</STRONG>, and <STRONG>wenclose</STRONG> relating to mouse interfacing are
- not part of XPG4, nor are they present in SVr4. See
- the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.
-
- <STRONG>o</STRONG> The routine <STRONG>mcprint</STRONG> was not present in any previous
- curses implementation. See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual
- page for details.
-
- <STRONG>o</STRONG> The routine <STRONG>wresize</STRONG> is not part of XPG4, nor is it
- present in SVr4. See the <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual page for
- details.
-
- <STRONG>o</STRONG> The WINDOW structure's internal details can be hidden
- from application programs. See <STRONG><A HREF="curs_opaque.3x.html">curs_opaque(3x)</A></STRONG> for
- the discussion of <STRONG>is_scrollok</STRONG>, etc.
-
- <STRONG>o</STRONG> This implementation can be configured to provide rudi-
- mentary support for multi-threaded applications. See
- <STRONG><A HREF="curs_threads.3x.html">curs_threads(3x)</A></STRONG> for details.
-
- <STRONG>o</STRONG> This implementation can also be configured to provide
- a set of functions which improve the ability to manage
- multiple screens. See <STRONG><A HREF="curs_sp_funcs.3x.html">curs_sp_funcs(3x)</A></STRONG> for details.
-
- In historic curses versions, delays embedded in the capa-
- bilities <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 implementa-
- tion, all padding is done by sending NUL bytes. This
- method is slightly more expensive, but narrows the inter-
- face to the UNIX kernel significantly and increases the
- package's portability correspondingly.
+ 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 features of its enhanced level.
+ Differences between X/Open Curses and <EM>ncurses</EM> are documented in the
+ "PORTABILITY" sections of applicable man pages.
-</PRE><H2><a name="h2-NOTES">NOTES</a></H2><PRE>
- The header file <STRONG><curses.h></STRONG> automatically includes the
- header files <STRONG><stdio.h></STRONG> and <STRONG><unctrl.h></STRONG>.
- If standard output from a <STRONG>ncurses</STRONG> program is re-directed
- to something which is not a tty, screen updates will be
- directed to standard error. This was an undocumented fea-
- ture of AT&T System V Release 3 curses.
+</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, <EM>ncurses</EM> checks pointer parameters, such
+ as those to <EM>WINDOW</EM> structures, to ensure that they are not null. This
+ is done primarily 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 occurred. Relying on this (or some

+ applications.
+
+
+</PRE><H3><a name="h3-Padding-Differences">Padding Differences</a></H3><PRE>
+ In historical <EM>curses</EM> implementations, delays embedded in the <EM>terminfo</EM>
+ capabilities <STRONG>carriage_return</STRONG> (<STRONG>cr</STRONG>), <STRONG>scroll_forward</STRONG> (<STRONG>ind</STRONG>), <STRONG>cursor_left</STRONG>
+ (<STRONG>cub1</STRONG>), <STRONG>form_feed</STRONG> (<STRONG>ff</STRONG>), and <STRONG>tab</STRONG> (<STRONG>ht</STRONG>) activated corresponding delay bits
+ in the Unix terminal driver. <EM>ncurses</EM> performs all padding by sending
+ NUL bytes to the device. This method is slightly more expensive, but
+ narrows the interface to the Unix kernel significantly and
+ correspondingly increases the package's portability.
+
+
+</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,
+
+ The inclusion of <EM>curses.h</EM> may make visible all symbols from the
+ headers <EM>stdio.h</EM>, <EM>term.h</EM>, <EM>termios.h</EM>, and <EM>wchar.h</EM>.
+
+ but does not finish the story. A more complete account follows.
+
+ <STRONG>o</STRONG> Starting with 4BSD <EM>curses</EM> (1980) all implementations have provided
+ a <EM>curses.h</EM> file.
+
+ BSD <EM>curses</EM> code included <EM>curses.h</EM> and <EM>unctrl.h</EM> from an internal
+ header file <EM>curses.ext</EM>, where "ext" abbreviated "externs".
+
+ The implementations of <EM>printw</EM> and <EM>scanw</EM> used undocumented internal
+ functions of the standard I/O library (<STRONG>_</STRONG><EM>doprnt</EM> and <STRONG>_</STRONG><EM>doscan</EM>), but
+ nothing in <EM>curses.h</EM> itself relied upon <EM>stdio.h</EM>.
+
+ <STRONG>o</STRONG> SVr2 <EM>curses</EM> added <EM>newterm</EM>, which relies upon <EM>stdio.h</EM> because its
+ function prototype employs the <EM>FILE</EM> type.
+
+ SVr4 <EM>curses</EM> added <EM>putwin</EM> and <EM>getwin</EM>, which also use <EM>stdio.h</EM>.
+
+ X/Open Curses specifies all three of these functions.
+
+ SVr4 <EM>curses</EM> and X/Open Curses do not require the developer to
+ include <EM>stdio.h</EM> before <EM>curses.h</EM>. Both document use of <EM>curses</EM> as
+ requiring only <EM>curses.h</EM>.
+
+ As a result, standard <EM>curses.h</EM> always includes <EM>stdio.h</EM>.
+
+ <STRONG>o</STRONG> X/Open Curses and SVr4 <EM>curses</EM> are inconsistent with respect to
+ <EM>unctrl.h</EM>.
+
+ As noted in <STRONG><A HREF="curs_util.3x.html">curs_util(3x)</A></STRONG>, <EM>ncurses</EM> includes <EM>unctrl.h</EM> from <EM>curses.h</EM>
+ (as SVr4 does).
+
+ <STRONG>o</STRONG> X/Open Curses's comments about <EM>term.h</EM> and <EM>termios.h</EM> may refer to
+ HP-UX and AIX.
+
+ HP-UX <EM>curses</EM> includes <EM>term.h</EM> from <EM>curses.h</EM> to declare <EM>setupterm</EM> in
+ <EM>curses.h</EM>, but <EM>ncurses</EM> and Solaris <EM>curses</EM> do not.
+
+ AIX <EM>curses</EM> includes <EM>term.h</EM> and termios.h<EM>.</EM> Again, <EM>ncurses</EM> and
+ Solaris <EM>curses</EM> do not.
+
+ <STRONG>o</STRONG> X/Open Curses says that <EM>curses.h</EM> <STRONG>may</STRONG> include <EM>term.h</EM>, but does not
+ require it to do so.
+
+ Some programs use functions declared in both <EM>curses.h</EM> and <EM>term.h</EM>,
+ and must include both header files in the same module. Very old
+ versions of AIX <EM>curses</EM> required inclusion of <EM>curses.h</EM> before
+ <EM>term.h</EM>.
+
+ The header files supplied by <EM>ncurses</EM> include the standard library
+ headers required for its declarations, so <EM>ncurses</EM>'s own header
+ files can be included in any order. But for portability, you
+ should include <EM>curses.h</EM> before <EM>term.h</EM>.
+
+ <STRONG>o</STRONG> X/Open Curses says "may make visible" because including a header
+ file does not necessarily make visible all of the symbols in it
+ (consider <STRONG>#ifdef</STRONG> and similar).
+
+ For instance, <EM>ncurses</EM>'s <EM>curses.h</EM> <STRONG>may</STRONG> include <EM>wchar.h</EM> if the proper
+ symbol is defined, and if <EM>ncurses</EM> is configured for wide-character
+ support. If <EM>wchar.h</EM> is included, its symbols <STRONG>may</STRONG> be made visible
+ depending on the value of the <STRONG>_XOPEN_SOURCE</STRONG> feature test macro.
+
+ <STRONG>o</STRONG> X/Open Curses mandates an application's inclusion of one standard C
+ library header in a special case: <EM>stdarg.h</EM> before <EM>curses.h</EM> to
+ prototype the functions <EM>vw</EM><STRONG>_</STRONG><EM>printw</EM> and <EM>vw</EM><STRONG>_</STRONG><EM>scanw</EM> (as well as the
+ obsolete <EM>vwprintw</EM> and <EM>vwscanw</EM>). Each of these takes a variadic
+ argument list, a <EM>va</EM><STRONG>_</STRONG><EM>list</EM> parameter, like that of <STRONG>printf(3)</STRONG>.
+
+ SVr3 <EM>curses</EM> introduced the two obsolete functions, and X/Open
+ Curses the others. In between, SVr4 <EM>curses</EM> provided for the
+ possibility that an application might include either <EM>varargs.h</EM> or
+ <EM>stdarg.h</EM>. These represented contrasting approaches to handling
+ variadic argument lists. The older interface, <EM>varargs.h</EM>, used a
+ pointer to <EM>char</EM> for variadic functions' <EM>va</EM><STRONG>_</STRONG><EM>list</EM> parameter. Later,
+ the list acquired its own standard data type, <EM>va</EM><STRONG>_</STRONG><EM>list</EM>, defined in
+ <EM>stdarg.h</EM>, empowering the compiler to check the types of a function
+ call's actual parameters against the formal ones declared in its
+ prototype.
+
+ No conforming implementations of X/Open Curses require an
+ application to include <EM>stdarg.h</EM> before <EM>curses.h</EM> because they either
+ have allowed for a special type, or, like <EM>ncurses</EM>, they include
+ <EM>stdarg.h</EM> themselves to provide a portable interface.
