.SH NAME
|
||
|
\fBdft_fgbg\fR \- use terminal's default colors
|
||
|
..
|
||
|
.SH SYNOPSIS
|
||
|
\fB#include <curses.h>\fP
|
||
|
|
||
|
\fBint use_default_colors(void);\fP
|
||
|
..
|
||
|
.SH DESCRIPTION
|
||
|
This is an extension to the curses library.
|
||
|
It is used with terminals that support ISO 6429 color, or equivalent.
|
||
|
These terminals allow the application to reset color to an unspecified
|
||
|
default value (e.g., with SGR 39 or SGR 49).
|
||
|
Because they are designed to support this, their design usually includes
|
||
|
features to change the default foreground or background colors so that
|
||
|
they do not match the assumption in XSI curses of white on black.
|
||
|
.PP
|
||
|
Applications that paint a colored background over the whole screen
|
||
|
are not adversely impacted by this type of terminal design.
|
||
|
However, there are applications that are designed to work with
|
||
|
the default background.
|
||
|
..
|
||
|
.SH RETURN VALUE
|
||
|
The function returns the integer \fBERR\fP upon failure and \fBOK\fP on success.
|
||
|
It will fail if either the terminal does not support
|
||
|
the \fIorig_pair\fP or \fIorig_colors\fP capability.
|
||
|
If the \fIinitialize_pair\fP capability is found, this causes an
|
||
|
error as well.
|
||
|
..
|
||
|
.SH NOTES
|
||
|
Associated with this extension, the \fBinit_pair\fR(3X) function accepts
|
||
|
negative arguments to specify default foreground or background
|
||
|
colors.
|
||
|
..
|
||
|
.SH PORTABILITY
|
||
|
These routines are specific to ncurses. They were not supported on
|
||
|
Version 7, BSD or System V implementations. It is recommended that
|
||
|
any code depending on them be conditioned using NCURSES_VERSION.
