Curses Library Functions cursbkgd(3CURSES)
NAME
cursbkgd, bkgd, bkgdset, wbkgdset, wbkgd - curses window
background manipulation routines
SYNOPSIS
cc [ flag ... ] file ... -lcurses [ library ... ]
#include
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 back-
ground of the named window. Background is a chtype consist-
ing 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 back-
ground 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 par-
ticular 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 combi-
nation 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 posi-
tions. 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 cursoutopts(3CURSES).
