CURSES_BACKGROUND(3)    NetBSD Library Functions Manual   CURSES_BACKGROUND(3)

NAME
     curses_background, bkgd, bkgdset, getbkgd, wbkgd, wbkgdset -- curses
     attribute manipulation routines

LIBRARY
     Curses Library (libcurses, -lcurses)

SYNOPSIS
     #include <curses.h>

     int
     bkgd(chtype);

     int
     bkgdset(chtype);

     chtype
     getbkgd(WINDOW *);

     int
     wbkgd(chtype);

     int
     wbkgdset(chtype);

DESCRIPTION
     These functions manipulate the background attributes on stdscr or on the
     specified window.

     The function wbkgdset(win, ch) sets the background attributes of the
     specified window win to ch.

     When the background attributes are set on a window, characters are added
     to the window with the logical OR of the background attributes and the
     character's attributes.  If both the background attribute and the charac-
     ter attribute contain color, the color of the character attribute is ren-
     dered.  If the background attribute contains a non-space character, then
     this character is added where the foreground character is a space charac-
     ter.

     Note that subwindows created from win inherit the background attributes
     of win.

     The function wbkgd(win, ch) sets the background attributes of the speci-
     fied window win to ch and also sets the rendition of every character
     position on that window, as if the characters had been newly added to
     win.  The rendition of characters on subwindows of win is also set to ch.

     The functions bkgdset(ch) and bkgd(ch) are equivalent to wbkgdset(stdscr,
     ch) and wbkgd(stdscr, ch), respectively.

     The function getbkgd(win) returns the background attributes for the win-
     dow win.

RETURN VALUES
     The functions wbkgdset() and wbkgd() return OK on success and ERR on
     failure.
