NAME

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

SYNOPSIS

       cc [ flag ... ] file ... -lcurses [ library ... ]
       #include <curses.h>

       int bkgd(chtype ch);

       void bkgdset(chtype ch);

       void wbkgdset(WINDOW *win, chtype ch);

       int wbkgd(WINDOW *win, chtype ch);

DESCRIPTION

       The  bkgdsets() 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 VALUES

       bkgd() and wbkgd() return the integer OK, or a non-negative integer, if immedok() is set. See curs_outopts(3CURSES).
