<H2>NAME</H2><PRE>
<STRONG>ncurses</STRONG> - CRT screen handling and optimization package
</PRE>
<H2>SYNOPSIS</H2><PRE>
<STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
</PRE>
<H2>DESCRIPTION</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 classic curses, which has been discontinued. This
describes <STRONG>ncurses</STRONG> version 5.9 (patch 20110404).
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 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.]
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>.
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.
<STRONG>Routine</STRONG> <STRONG>and</STRONG> <STRONG>Argument</STRONG> <STRONG>Names</STRONG>
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:
ncurses
the "normal" library, which handles 8-bit
characters. The normal (8-bit) library stores
characters 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>.
ncursesw
the so-called "wide" library, which handles
multibyte characters (see the section on
<STRONG>ALTERNATE</STRONG> <STRONG>CONFIGURATIONS</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 charac-
ters:
<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 char-
acters 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 sepa-
rate 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 "nor-
mal" library. There is a naming convention
which relates many of the normal/wide vari-
ants: a "_w" is inserted into the name. For
example, <STRONG>waddch</STRONG> becomes <STRONG>wadd_wch</STRONG>.
<STRONG>Routine</STRONG> <STRONG>Name</STRONG> <STRONG>Index</STRONG>
The following table lists each <STRONG>curses</STRONG> routine and the name

<H2>RETURN VALUE</H2><PRE>
Routines that return an integer return <STRONG>ERR</STRONG> upon failure
and an integer value other than <STRONG>ERR</STRONG> upon successful com-
pletion, unless otherwise noted in the routine descrip-
tions.
All macros return the value of the <STRONG>w</STRONG> version, except
<STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>, and <STRONG>getmaxyx</STRONG>. The
return values of <STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>,
and <STRONG>getmaxyx</STRONG> are undefined (i.e., these should not be used
as the right-hand side of assignment statements).
Routines that return pointers return <STRONG>NULL</STRONG> on error.
</PRE>
<H2>ENVIRONMENT</H2><PRE>
The following environment symbols are useful for customiz-
ing the runtime behavior of the <STRONG>ncurses</STRONG> 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, <STRONG>ncurses</STRONG> 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 <STRONG>cmdch</STRONG> capability) of the loaded terminfo
entries to the value of this symbol. Very few ter-
minfo entries provide this feature.
Because this name is also used in development envi-
ronments to represent the C compiler's name, <STRONG>ncurses</STRONG>
ignores it if it does not happen to be a single char-
acter.
COLUMNS
Specify the width of the screen in characters.
Applications running in a windowing environment usu-
ally are able to obtain the width of the window in
which they are executing. 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
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, <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 exter-
nal environment (including system calls) to determine
the screen size.
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 vari-
able 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 char-
acter 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 imple-
mentation provides a global variable with the same
name. Portable applications should not rely upon the
presence of ESCDELAY in either form, but setting the
environment variable rather than the global variable
does not create problems when compiling an applica-
tion.
HOME Tells <STRONG>ncurses</STRONG> 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, <STRONG>ncurses</STRONG> uses
132.
NCURSES_ASSUMED_COLORS
Override the compiled-in assumption that the termi-
nal's default colors are white-on-black (see
<STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG>). You may set the foreground and
background color values with this environment vari-
able by proving a 2-element list: foreground,back-
ground. For example, to tell ncurses to not assume
anything about the colors, set this to "-1,-1". To
make it green-on-black, set it to "2,0". Any posi-
tive value from zero to the terminfo <STRONG>max_colors</STRONG> value
is allowed.
NCURSES_GPM_TERMS
This applies only to ncurses configured to use the
GPM interface.
If present, the environment variable is a list of one
or more terminal names against which the TERM envi-
ronment variable is matched. Setting it to an empty
value disables the GPM interface; using the built-in
support for xterm, etc.
If the environment variable is absent, ncurses will
attempt to open GPM if TERM contains "linux".
NCURSES_NO_HARD_TABS
<STRONG>Ncurses</STRONG> may use tabs as part of the cursor movement
optimization. In some cases, your terminal driver
may not handle these properly. Set this environment
variable to disable the feature. You can also adjust
your <STRONG>stty</STRONG> settings to avoid the problem.
NCURSES_NO_MAGIC_COOKIES
Some terminals use a magic-cookie feature which
requires special handling to make highlighting and
other video attributes display properly. You can
suppress the highlighting entirely for these termi-
nals by setting this environment variable.
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 applica-
tions. 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., tim-
ing. Unless a hardware terminal is interfaced into a
terminal concentrator (which does flow control), it
(or your application) must manage dataflow, prevent-
ing 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 <EM>flash</EM>.
NCURSES_NO_SETBUF
Normally <STRONG>ncurses</STRONG> enables buffered output during ter-
minal initialization. This is done (as in SVr4
curses) for performance reasons. For testing pur-
poses, both of <STRONG>ncurses</STRONG> 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_NO_UTF8_ACS
During initialization, the <STRONG>ncurses</STRONG> library checks for
special cases where VT100 line-drawing (and the cor-
responding alternate character set capabilities)
described in the terminfo are known to be missing.
Specifically, when running 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 termi-
nal emulators.
When setting this variable, you should set it to a
nonzero value. Setting it to zero (or to a nonnum-
ber) disables the special check for "linux" and
"screen".
As an alternative to the environment variable,
ncurses checks for an extended terminfo capability
<STRONG>U8</STRONG>. This is a numeric capability which can be com-
piled using <STRONG>tic</STRONG> <STRONG>-x</STRONG>. For example
# linux console, if patched to provide working
# VT100 shift-in/shift-out, with corresponding font.
linux-vt100|linux console with VT100 line-graphics,
U8#0, use=linux,
# uxterm with vt100Graphics resource set to false
xterm-utf8|xterm relying on UTF-8 line-graphics,
U8#1, use=xterm,
The name "U8" is chosen to be two characters, to per-
mit it to be used by applications that use ncurses'
termcap interface.
NCURSES_TRACE
During initialization, the <STRONG>ncurses</STRONG> debugging library
checks the NCURSES_TRACE symbol. If it is defined,
to a numeric value, <STRONG>ncurses</STRONG> calls the <STRONG>trace</STRONG> function,
using that value as the argument.
The argument values, which are defined in <STRONG>curses.h</STRONG>,
provide several types of information. When running
with traces enabled, your application will write the
file <STRONG>trace</STRONG> to the current directory.
TERM Denotes your terminal type. Each terminal type is
distinct, though many are similar.
TERMCAP
If the <STRONG>ncurses</STRONG> library has been configured with <EM>term-</EM>
<EM>cap</EM> support, <STRONG>ncurses</STRONG> 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 <STRONG>ncurses</STRONG> to ignore the usual place for this
information, e.g., /etc/termcap.
TERMINFO
Overrides the directory in which <STRONG>ncurses</STRONG> 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:
<STRONG>o</STRONG> the last directory to which <STRONG>ncurses</STRONG> wrote, if
any, is searched first
<STRONG>o</STRONG> the directory specified by the TERMINFO symbol
<STRONG>o</STRONG> $HOME/.terminfo
<STRONG>o</STRONG> directories listed in the TERMINFO_DIRS symbol
<STRONG>o</STRONG> one or more directories whose names are config-
ured and compiled into the ncurses library, e.g.,
/usr/share/terminfo
TERMINFO_DIRS
Specifies a list of directories to search for termi-
nal descriptions. The list is separated by colons
(i.e., ":") on Unix, semicolons on OS/2 EMX. 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 <STRONG>ncurses</STRONG>
checks the TERMPATH symbol. This is a list of file-
names separated by spaces or colons (i.e., ":") on
Unix, semicolons on OS/2 EMX. If the TERMPATH symbol
is not set, <STRONG>ncurses</STRONG> 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.
</PRE>
<H2>ALTERNATE CONFIGURATIONS</H2><PRE>
Several different configurations are possible, depending
on the configure script options used when building
<STRONG>ncurses</STRONG>. There are a few main options whose effects are
visible to the applications developer using <STRONG>ncurses</STRONG>:
--disable-overwrite
The standard include for <STRONG>ncurses</STRONG> is as noted in <STRONG>SYN-</STRONG>
<STRONG>OPSIS</STRONG>:
<STRONG>#include</STRONG> <STRONG><curses.h></STRONG>
This option is used to avoid filename conflicts when
<STRONG>ncurses</STRONG> is not the main implementation of curses of
the computer. If <STRONG>ncurses</STRONG> 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 define <STRONG>_XOPEN_SOURCE_EXTENDED</STRONG> when com-
piling for the wide-character library to use the
extended (wide-character) functions. The <STRONG>curses.h</STRONG>
file which is installed for the wide-character
library is designed to be compatible with the normal
library's header. Only the size of the <STRONG>WINDOW</STRONG> struc-
ture differs, and very few applications require more
than a pointer to <STRONG>WINDOW</STRONG>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-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-trace
The <STRONG>trace</STRONG> function normally resides in the debug
library, but it is sometimes useful to configure this
in the shared library. Configure scripts should
check for the function's existence rather than assum-
ing it is always in the debug library.

<H2>EXTENSIONS</H2><PRE>
The <STRONG>ncurses</STRONG> library can be compiled with an option
(<STRONG>-DUSE_GETCAP</STRONG>) that falls back to the old-style /etc/term-
cap file if the terminal setup code cannot find a terminfo
entry corresponding to <STRONG>TERM</STRONG>. Use of this feature is not
recommended, as it essentially includes an entire termcap
compiler in the <STRONG>ncurses</STRONG> startup code, at significant cost
in core and startup cycles.
The <STRONG>ncurses</STRONG> library includes facilities for capturing
mouse events on certain terminals (including xterm). See
the <STRONG><A HREF="curs_mouse.3x.html">curs_mouse(3x)</A></STRONG> manual page for details.
The <STRONG>ncurses</STRONG> library includes facilities for responding to
window resizing events, e.g., when running in an xterm.
See the <STRONG><A HREF="resizeterm.3x.html">resizeterm(3x)</A></STRONG> and <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG> manual pages for
details. In addition, the library may be configured with
a SIGWINCH handler.
The <STRONG>ncurses</STRONG> library extends the fixed set of function key
capabilities of terminals by allowing the application
designer to define additional key sequences at runtime.
See the <STRONG><A HREF="define_key.3x.html">define_key(3x)</A></STRONG> <STRONG><A HREF="key_defined.3x.html">key_defined(3x)</A></STRONG>, and <STRONG><A HREF="keyok.3x.html">keyok(3x)</A></STRONG> man-
ual pages for details.
The <STRONG>ncurses</STRONG> library can exploit the capabilities of termi-
nals which implement the ISO-6429 SGR 39 and SGR 49 con-
trols, 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 col-
ored text on a background whose color is set indepen-
dently, providing better control over color contrasts.
See the <STRONG><A HREF="default_colors.3x.html">default_colors(3x)</A></STRONG> manual page for details.
The <STRONG>ncurses</STRONG> library includes a function for directing
application output to a printer attached to the terminal
device. See the <STRONG><A HREF="curs_print.3x.html">curs_print(3x)</A></STRONG> manual page for details.
</PRE>
<H2>PORTABILITY</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.
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

<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.

<H2>NOTES</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.
