use_default_colors(3) use_default_colors(3)
NAME
dft_fgbg - use terminal's default colors
SYNOPSIS
#include <curses.h>
int use_default_colors(void);
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 assump-
tion in XSI curses of white on black.
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.
RETURN VALUE
The function returns the integer ERR upon failure and OK
on success. It will fail if either the terminal does not
support the orig_pair or orig_colors capability. If the
initialize_pair capability is found, this causes an error
as well.
NOTES
Associated with this extension, the init_pair(3) function
accepts negative arguments to specify default foreground
or background colors.
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 con-
ditioned using NCURSES_VERSION.
