<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
reasonable optimization. This implementation is ``new
curses'' (ncurses) and is the approved replacement for
4.4BSD classic curses, which has been discontinued.
The <STRONG>ncurses</STRONG> routines emulate the <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG> library of
System V Release 4 UNIX, and the XPG4 curses standard (XSI
curses) but the <STRONG>ncurses</STRONG> library is freely redistributable
in source form. Differences from the SVr4 curses are
summarized under the EXTENSIONS and BUGS sections below
and described in detail in the EXTENSIONS and BUGS
sections of individual man pages.
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.
The <STRONG>ncurses</STRONG> 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.
To initialize the routines, the routine <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>
must be called 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 following 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
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
<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
structures, 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
windows 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 which 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
displayed. 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
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, <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 effect 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
program 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 definition 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
available.
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
values <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
routines prefixed with <STRONG>w</STRONG> require a window argument. The
routines prefixed with <STRONG>p</STRONG> require a pad argument. Those
without 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>WINDOW</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>. The
variables <EM>ch</EM> and <EM>attrs</EM> below are always of type <STRONG>chtype</STRONG>.
The types <STRONG>WINDOW</STRONG>, <STRONG>SCREEN</STRONG>, <STRONG>bool</STRONG>, and <STRONG>chtype</STRONG> are defined in
<STRONG><curses.h></STRONG>. The type <STRONG>TERMINAL</STRONG> is defined in <STRONG><term.h></STRONG>.
All other arguments are integers.

<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
completion, unless otherwise noted in the routine
descriptions.
All macros return the value of the <STRONG>w</STRONG> version, except
<STRONG>setscrreg</STRONG>, <STRONG>wsetscrreg</STRONG>, <STRONG>getyx</STRONG>, <STRONG>getbegyx</STRONG>, <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 (<EM>i</EM>.<EM>e</EM>., 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
customizing 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
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,
<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. 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, <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 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 <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_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 <EM>flash</EM>.
NCURSES_NO_SETBUF
Normally <STRONG>ncurses</STRONG> enables buffered output during
terminal initialization. This is done (as in SVr4
curses) for performance reasons. For testing
purposes, 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_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>termcap</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:
- the last directory to which <STRONG>ncurses</STRONG> 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., ":") 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
filenames 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>FILES</H2><PRE>
/usr/share/tabset
directory containing initialization files for the
terminal capability database /usr/share/terminfo
terminal capability database
</PRE>
<H2>SEE ALSO</H2><PRE>
<STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG> and related pages whose names begin "curs_"
for detailed routine descriptions.
</PRE>
<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/termcap 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> and <STRONG><A HREF="keyok.3x.html">keyok(3x)</A></STRONG> manual pages for
details.
The <STRONG>ncurses</STRONG> 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 <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
conformant with the XSI Curses standard. Certain portions
of the EXTENDED XSI Curses functionality (including color
support) are supported. The following EXTENDED XSI Curses
calls in support of wide (multibyte) characters are not
yet implemented: <STRONG>pecho_wchar</STRONG>, <STRONG>slk_wset</STRONG>.
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.
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.
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.
The routines <STRONG>getmouse</STRONG>, <STRONG>mousemask</STRONG>, <STRONG>ungetmouse</STRONG>,
<STRONG>mouseinterval</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.
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.
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.
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 NUL sends. This
method is slightly more expensive, but narrows the
interface to the UNIX kernel significantly and increases
the package's portability correspondingly.
In the XSI standard and SVr4 manual pages, many entry
points have prototype arguments of the for <STRONG>char</STRONG> <STRONG>*const</STRONG> (or
<STRONG>cchar_t</STRONG> <STRONG>*const</STRONG>, or <STRONG>wchar_t</STRONG> <STRONG>*const</STRONG>, or <STRONG>void</STRONG> <STRONG>*const</STRONG>).
Depending on one's interpretation of the ANSI C standard
(see section 3.5.4.1), these declarations are either (a)
meaningless, or (b) meaningless and illegal. The
declaration <STRONG>const</STRONG> <STRONG>char</STRONG> <STRONG>*x</STRONG> is a modifiable pointer to
unmodifiable data, but <STRONG>char</STRONG> <STRONG>*const</STRONG> <STRONG>x</STRONG>' is an unmodifiable
pointer to modifiable data. Given that C passes arguments
by value, <STRONG><type></STRONG> <STRONG>*const</STRONG> as a formal type is at best
dubious. Some compilers choke on the prototypes.
Therefore, in this implementation, they have been changed
to <STRONG>const</STRONG> <STRONG><type></STRONG> <STRONG>*</STRONG> globally.
</PRE>
<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
feature of AT&T System V Release 3 curses.
