NAME
     curs_bkgd:	 bkgdset, wbkgdset, bkgd, wbkgd - curses window background
     manipulation routines

SYNOPSIS
     #include <curses.h>

     void bkgdset(chtype ch);
     void wbkgdset(WINDOW *win, chtype ch);
     int bkgd(chtype ch);
     int wbkgd(WINDOW *win, chtype ch);

DESCRIPTION
     The bkgdset and wbkgdset routines manipulate the background of the named
     window.  Background is a chtype consisting of any combination of
     attributes and a character.  The attribute part of the background is
     combined (ORed) with all non-blank characters that are written into the
     window  with waddch.  Both the character and attribute parts of the
     background are combined with the blank characters.	 The background
     becomes a property of the character and moves with the character through
     any scrolling and insert/delete line/character operations.	 To the extent
     possible on a particular terminal, the attribute part of the background
     is displayed as the graphic rendition of the character put on the screen.

     The bkgd and wbkgd routines combine the new background with every
     position in the window.  Background is any combination of attributes and
     a character.  Only the attribute part is used to set the background of
     non-blank characters, while both character and attributes are used for
     blank positions.  To the extent possible on a particular terminal, the
     attribute part of the background is displayed as the graphic rendition of
     the character put on the screen.

RETURN VALUE
     bkgd and wbkgd return the integer OK, or a non-negative integer, if
     immedok is set.

NOTES
     The header file <curses.h> automatically includes the header files
     <stdio.h> and <unctrl.h>.

     Note that bkgdset and bkgd may be macros.
