.SH NAME
|
|
|
|
|
\fBncurses\fR - CRT screen handling and optimization package
|
|
|
|
|
.SH SYNOPSIS
|
|
|
|
|
\fB#include <curses.h>\fR
|
|
|
|
|
.br
|
|
|
|
|
.SH DESCRIPTION
|
|
|
|
|
The \fBncurses\fR 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 \fBncurses\fR routines emulate the \fBcurses\fR(3X) library of System V
|
|
|
|
|
Release 4 UNIX, and the XPG4 curses standard (XSI curses) but the \fBncurses\fR
|
|
|
|
|
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 \fB-lncurses\fR option,
|
|
|
|
|
or (if it has been generated) with the debugging library \fB-lncurses_g\fR.
|
|
|
|
|
(Your system integrator may also have installed these libraries under
|
|
|
|
|
the names \fB-lcurses\fR and \fB-lcurses_g\fR.)
|
|
|
|
|
The ncurses_g library generates trace logs (in a file called 'trace' in the
|
|
|
|
|
current directory) that describe curses actions.
|
|
|
|
|
|
|
|
|
|
The \fBncurses\fR package supports: overall screen, window and pad
|
|
|
|
|
manipulation; output to windows and pads; reading terminal input; control over
|
|
|
|
|
terminal and \fBcurses\fR 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 \fBinitscr\fR or \fBnewterm\fR
|
|
|
|
|
must be called before any of the other routines that deal with windows
|
|
|
|
|
and screens are used. The routine \fBendwin\fR 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:
|
|
|
|
|
|
|
|
|
|
\fBinitscr(); cbreak(); noecho();\fR
|
|
|
|
|
|
|
|
|
|
Most programs would additionally use the sequence:
|
|
|
|
|
|
|
|
|
|
\fBnonl();\fR
|
|
|
|
|
\fBintrflush(stdscr, FALSE);\fR
|
|
|
|
|
\fBkeypad(stdscr, TRUE);\fR
|
|
|
|
|
|
|
|
|
|
Before a \fBcurses\fR 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 \fBtput init\fR command
|
|
|
|
|
after the shell environment variable \fBTERM\fR has been exported.
|
|
|
|
|
\fBtset(1)\fR is usually responsible for doing this.
|
|
|
|
|
[See \fBterminfo\fR(\*n) for further details.]
|
|
|
|
|
|
|
|
|
|
The \fBncurses\fR library permits manipulation of data structures,
|
|
|
|
|
called \fIwindows\fR, which can be thought of as two-dimensional
|
|
|
|
|
arrays of characters representing all or part of a CRT screen. A
|
|
|
|
|
default window called \fBstdscr\fR, which is the size of the terminal
|
|
|
|
|
screen, is supplied. Others may be created with \fBnewwin\fR.
|
|
|
|
|
|
|
|
|
|
Note that \fBcurses\fR does not handle overlapping windows, that's done by
|
|
|
|
|
the \fBpanel\fR(3X) library. This means that you can either use
|
|
|
|
|
\fBstdscr\fR or divide the screen into tiled windows and not using
|
|
|
|
|
\fBstdscr\fR at all. Mixing the two will result in unpredictable, and
|
|
|
|
|
undesired, effects.
|
|
|
|
|
|
|
|
|
|
Windows are referred to by variables declared as \fBWINDOW *\fR.
|
|
|
|
|
These data structures are manipulated with routines described here and
|
|
|
|
|
elsewhere in the \fBncurses\fR manual pages. Among which the most basic
|
|
|
|
|
routines are \fBmove\fR and \fBaddch\fR. More general versions of
|
|
|
|
|
these routines are included with names beginning with \fBw\fR,
|
|
|
|
|
allowing the user to specify a window. The routines not beginning
|
|
|
|
|
with \fBw\fR affect \fBstdscr\fR.)
|
|
|
|
|
|
|
|
|
|
After using routines to manipulate a window, \fBrefresh\fR is called,
|
|
|
|
|
telling \fBcurses\fR to make the user's CRT screen look like
|
|
|
|
|
\fBstdscr\fR. The characters in a window are actually of type
|
|
|
|
|
\fBchtype\fR, (character and attribute data) so that other information
|
|
|
|
|
about the character may also be stored with each character.
|
|
|
|
|
|
|
|
|
|
Special windows called \fIpads\fR 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 \fBcurs_pad\fR(3X) 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, \fBcurses\fR 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 \fB<curses.h>\fR,
|
|
|
|
|
such as \fBA_REVERSE\fR, \fBACS_HLINE\fR, and \fBKEY_LEFT\fR.
|
|
|
|
|
|
|
|
|
|
If the environment variables \fBLINES\fR and \fBCOLUMNS\fR are set, or if the
|
|
|
|
|
program is executing in a window environment, line and column information in
|
|
|
|
|
the environment will override information read by \fIterminfo\fR. This would
|
|
|
|
|
effect a program running in an AT&T 630 layer, for example, where the size of a
|
|
|
|
|
screen is changeable (see \fBENVIRONMENT\fR).
|
|
|
|
|
|
|
|
|
|
If the environment variable \fBTERMINFO\fR is defined, any program using
|
|
|
|
|
\fBcurses\fR checks for a local terminal definition before checking in the
|
|
|
|
|
standard place. For example, if \fBTERM\fR is set to \fBatt4424\fR, then the
|
|
|
|
|
compiled terminal definition is found in
|
|
|
|
|
|
|
|
|
|
\fB\*d/a/att4424\fR.
|
|
|
|
|
|
|
|
|
|
(The \fBa\fR is copied from the first letter of \fBatt4424\fR to avoid
|
|
|
|
|
creation of huge directories.) However, if \fBTERMINFO\fR is set to
|
|
|
|
|
\fB$HOME/myterms\fR, \fBcurses\fR first checks
|
|
|
|
|
|
|
|
|
|
\fB$HOME/myterms/a/att4424\fR,
|
|
|
|
|
|
|
|
|
|
and if that fails, it then checks
|
|
|
|
|
|
|
|
|
|
\fB\*d/a/att4424\fR.
|
|
|
|
|
|
|
|
|
|
This is useful for developing experimental definitions or when write
|
|
|
|
|
permission in \fB\*d\fR is not available.
|
|
|
|
|
|
|
|
|
|
The integer variables \fBLINES\fR and \fBCOLS\fR are defined in
|
|
|
|
|
\fB<curses.h>\fR and will be filled in by \fBinitscr\fR with the size of the
|
|
|
|
|
screen. The constants \fBTRUE\fR and \fBFALSE\fR have the values \fB1\fR and
|
|
|
|
|
\fB0\fR, respectively.
|
|
|
|
|
|
|
|
|
|
The \fBcurses\fR routines also define the \fBWINDOW *\fR variable \fBcurscr\fR
|
|
|
|
|
which is used for certain low-level operations like clearing and redrawing a
|
|
|
|
|
screen containing garbage. The \fBcurscr\fR can be used in only a few
|
|
|
|
|
routines.
|
|
|
|
|
|
|
|
|
|
.SS Routine and Argument Names
|
|
|
|
|
Many \fBcurses\fR routines have two or more versions. The routines prefixed
|
|
|
|
|
with \fBw\fR require a window argument. The routines prefixed with \fBp\fR
|
|
|
|
|
require a pad argument. Those without a prefix generally use \fBstdscr\fR.
|
|
|
|
|
|
|
|
|
|
The routines prefixed with \fBmv\fR require a \fIy\fR and \fIx\fR
|
|
|
|
|
coordinate to move to before performing the appropriate action. The
|
|
|
|
|
\fBmv\fR routines imply a call to \fBmove\fR before the call to the
|
|
|
|
|
other routine. The coordinate \fIy\fR always refers to the row (of
|
|
|
|
|
the window), and \fIx\fR always refers to the column. The upper
|
|
|
|
|
left-hand corner is always (0,0), not (1,1).
|
|
|
|
|
|
|
|
|
|
The routines prefixed with \fBmvw\fR take both a window argument and
|
|
|
|
|
\fIx\fR and \fIy\fR coordinates. The window argument is always
|
|
|
|
|
specified before the coordinates.
|
|
|
|
|
|
|
|
|
|
In each case, \fIwin\fR is the window affected, and \fIpad\fR is the
|
|
|
|
|
pad affected; \fIwin\fR and \fIpad\fR are always pointers to type
|
|
|
|
|
\fBWINDOW\fR.
|
|
|
|
|
|
|
|
|
|
Option setting routines require a Boolean flag \fIbf\fR with the value
|
|
|
|
|
\fBTRUE\fR or \fBFALSE\fR; \fIbf\fR is always of type \fBbool\fR. The
|
|
|
|
|
variables \fIch\fR and \fIattrs\fR below are always of type
|
|
|
|
|
\fBchtype\fR. The types \fBWINDOW\fR, \fBSCREEN\fR, \fBbool\fR, and
|
|
|
|
|
\fBchtype\fR are defined in \fB<curses.h>\fR. The type \fBTERMINAL\fR
|
|
|
|
|
is defined in \fB<term.h>\fR. All other arguments are integers.
|
|
|

.SH RETURN VALUE
|
|
|
|
|
Routines that return an integer return \fBERR\fR upon failure and an
|
|
|
|
|
integer value other than \fBERR\fR upon successful completion, unless
|
|
|
|
|
otherwise noted in the routine descriptions.
|
|
|
|
|
|
|
|
|
|
All macros return the value of the \fBw\fR version, except \fBsetscrreg\fR,
|
|
|
|
|
\fBwsetscrreg\fR, \fBgetyx\fR, \fBgetbegyx\fR, \fBgetmaxyx\fR. The return
|
|
|
|
|
values of \fBsetscrreg\fR, \fBwsetscrreg\fR, \fBgetyx\fR, \fBgetbegyx\fR, and
|
|
|
|
|
\fBgetmaxyx\fR are undefined (\fIi\fR.\fIe\fR., these should not be used as the
|
|
|
|
|
right-hand side of assignment statements).
|
|
|
|
|
|
|
|
|
|
Routines that return pointers return \fBNULL\fR on error.
|
|
|
|
|
.SH ENVIRONMENT
|
|
|
|
|
The following environment symbols are useful for customizing the
|
|
|
|
|
runtime behavior of the \fBncurses\fR library. The most important
|
|
|
|
|
ones have been already discussed in detail.
|
|
|
|
|
.TP 5
|
|
|
|
|
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 \fBncurses\fR uses 9600.
|
|
|
|
|
This allows testers to construct repeatable test-cases
|
|
|
|
|
that take into account costs that depend on baudrate.
|
|
|
|
|
.TP 5
|
|
|
|
|
CC
|
|
|
|
|
When set, change occurrences of the command_character
|
|
|
|
|
(i.e., the \fBcmdch\fP capability)
|
|
|
|
|
of the loaded terminfo entries to the value of this symbol.
|
|
|
|
|
Very few terminfo entries provide this feature.
|
|
|
|
|
.TP 5
|
|
|
|
|
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,
|
|
|
|
|
\fBncurses\fR uses the size which may be specified in the terminfo database
|
|
|
|
|
(i.e., the \fBcols\fR 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, \fBlines\fR and \fBcols\fR should not be specified in
|
|
|
|
|
a terminal description for terminals which are run as emulations.
|
|
|
|
|
|
|
|
|
|
Use the \fBuse_env\fR function to disable this feature.
|
|
|
|
|
.TP 5
|
|
|
|
|
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.
|
|
|
|
|
.TP 5
|
|
|
|
|
HOME
|
|
|
|
|
Tells \fBncurses\fR where your home directory is.
|
|
|
|
|
That is where it may read and write auxiliary terminal descriptions:
|
|
|
|
|
|
|
|
|
|
$HOME/.termcap
|
|
|
|
|
.br
|
|
|
|
|
$HOME/.terminfo
|
|
|
|
|
.TP 5
|
|
|
|
|
LINES
|
|
|
|
|
Like COLUMNS, specify the height of the screen in characters.
|
|
|
|
|
See COLUMNS for a detailed description.
|
|
|
|
|
.TP 5
|
|
|
|
|
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
|
|
|
|
|
.br
|
|
|

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 \fIflash\fR.
|
|
|
|
|
.TP 5
|
|
|
|
|
NCURSES_NO_SETBUF
|
|
|
|
|
Normally \fBncurses\fR enables buffered output during terminal initialization.
|
|
|
|
|
This is done (as in SVr4 curses) for performance reasons.
|
|
|
|
|
For testing purposes, both of \fBncurses\fR 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.
|
|
|
|
|
.TP 5
|
|
|
|
|
NCURSES_TRACE
|
|
|
|
|
During initialization, the \fBncurses\fR debugging library
|
|
|
|
|
checks the NCURSES_TRACE symbol.
|
|
|
|
|
If it is defined, to a numeric value, \fBncurses\fR calls the \fBtrace\fR
|
|
|
|
|
function, using that value as the argument.
|
|
|
|
|
|
|
|
|
|
The argument values, which are defined in \fBcurses.h\fR, provide several
|
|
|
|
|
types of information.
|
|
|
|
|
When running with traces enabled, your application will write the
|
|
|
|
|
file \fBtrace\fR to the current directory.
|
|
|
|
|
.TP 5
|
|
|
|
|
TERM
|
|
|
|
|
Denotes your terminal type.
|
|
|
|
|
Each terminal type is distinct, though many are similar.
|
|
|
|
|
.TP 5
|
|
|
|
|
TERMCAP
|
|
|
|
|
If the \fBncurses\fR library has been configured with \fItermcap\fR
|
|
|
|
|
support, \fBncurses\fR 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 \fBncurses\fR to ignore
|
|
|
|
|
the usual place for this information, e.g., /etc/termcap.
|
|
|
|
|
.TP 5
|
|
|
|
|
TERMINFO
|
|
|
|
|
Overrides the directory in which \fBncurses\fR 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:
|

Specifies a list of directories to search for terminal descriptions.
|
2001-05-17 08:21:06 +00:00
|
|
|
The list is separated by colons (i.e., ":") on Unix, semicolons on OS/2 EMX.
|
1999-08-24 01:06:48 +00:00
|
|
|
All of the terminal descriptions are in terminfo form, which makes
|
|
|
|
|
a subdirectory named for the first letter of the terminal names therein.
|
|
|
|
|
.TP 5
|
|
|
|
|
TERMPATH
|
|
|
|
|
If TERMCAP does not hold a file name then \fBncurses\fR checks
|
|
|
|
|
the TERMPATH symbol.
|
2001-05-17 08:21:06 +00:00
|
|
|
This is a list of filenames separated by spaces or colons (i.e., ":") on Unix, semicolons on OS/2 EMX.
|
1999-08-24 01:06:48 +00:00
|
|
|
If the TERMPATH symbol is not set, \fBncurses\fR looks in the files
|
|
|
|
|
/etc/termcap, /usr/share/misc/termcap and $HOME/.termcap, in that order.
|

.SH EXTENSIONS
|
|
|
|
|
The \fBncurses\fR library can be compiled with an option (\fB-DUSE_GETCAP\fR)
|
|
|
|
|
that falls back to the old-style /etc/termcap file if the terminal setup code
|
|
|
|
|
cannot find a terminfo entry corresponding to \fBTERM\fR. Use of this feature
|
|
|
|
|
is not recommended, as it essentially includes an entire termcap compiler in
|
|
|
|
|
the \fBncurses\fR startup code, at significant cost in core and startup cycles.
|
|
|
|
|
|
|
|
|
|
The \fBncurses\fR library includes facilities for capturing mouse events on
|
|
|
|
|
certain terminals (including xterm). See the \fBcurs_mouse\fR(3X)
|
|
|
|
|
manual page for details.
|
|
|
|
|
|
|
|
|
|
The \fBncurses\fR library includes facilities for responding to window
|
|
|
|
|
resizing events, e.g., when running in an xterm.
|
|
|
|
|
See the \fBresizeterm\fR(3X)
|
|
|
|
|
and \fBwresize\fR(3X) manual pages for details.
|
|
|
|
|
In addition, the library may be configured with a SIGWINCH handler.
|
|
|
|
|
|
|
|
|
|
The \fBncurses\fR 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 \fBdefine_key\fR(3X)
|
|
|
|
|
and \fBkeyok\fR(3X) manual pages for details.
|
|
|
|
|
|
|
|
|
|
The \fBncurses\fR 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.
|
2002-05-21 05:30:25 +00:00

|
|

1999-08-24 01:06:48 +00:00
|
|
|
|
|
|
|
|
The \fBncurses\fR library includes a function for directing application output
|
|
|
|
|
to a printer attached to the terminal device. See the \fBcurs_print\fR(3X)
|
|
|
|
|
manual page for details.

.SH PORTABILITY
|
|
|
|
|
The \fBncurses\fR 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:
|
|
|
|
|
\fBpecho_wchar\fP,
|

|
|
|
|
|
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 \fBchar *const\fR (or \fBcchar_t *const\fR, or
|
|
|
|
|
\fBwchar_t *const\fR, or \fBvoid *const\fR). 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
|
|
|
|
|
\fBconst char *x\fR is a modifiable pointer to unmodifiable data, but
|
|
|
|
|
\fBchar *const x\fR' is
|
|
|
|
|
an unmodifiable pointer to modifiable data. Given that C passes arguments by
|
|
|
|
|
value, \fB<type> *const\fR as a formal type is at best dubious. Some compilers
|
|
|
|
|
choke on the prototypes. Therefore, in this implementation, they have been
|
|
|
|
|
changed to \fBconst <type> *\fR globally.
|
|
|
|
|
.SH NOTES
|
|
|
|
|
The header file \fB<curses.h>\fR automatically includes the header files
|
|
|
|
|
\fB<stdio.h>\fR and \fB<unctrl.h>\fR.
|
|
|
|
|
|
|
|
|
|
If standard output from a \fBncurses\fR 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.
