CURSES_DEFAULT_COLORS(3)				   BSD Library Functions Manual 				  CURSES_DEFAULT_COLORS(3)

NAME

     curses_default_colors, assume_default_colors, use_default_colors -- curses default colors setting routines

LIBRARY

     Curses Library (libcurses, -lcurses)

SYNOPSIS

     #include <curses.h>

     int
     assume_default_colors(short fore, short back);

     int
     use_default_colors();

DESCRIPTION

     These functions tell the curses library to set the default colors or to use the terminal's default colors instead of using the default colors
     for curses applications (which are white foreground on black background).

     The function assume_default_colors(fore, back) sets the default colors to foreground color fore and background color back.  If a value of -1
     is used for a color, then the terminal default color is used for that color.

     The function use_default_colors() sets both the foreground and background colors to the terminal default colors.  This is equivalent to
     assume_default_colors(-1, -1).

RETURN VALUES

     These functions return OK on success and ERR on failure.

SEE ALSO

     curses_color(3)

STANDARDS

     These functions are based on ncurses extensions to the curses standards.

HISTORY

     These functions first appeared in NetBSD 2.0.
