           dft_fgbg - use terminal's default colors

## SYNOPSIS

           #include

           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(3X) 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.
