NAME
bkgrnd, wbkgrnd, bkgrndset, wbkgrndset, getbkgrnd, wgetbkgrnd - curses
window complex background manipulation routines
SYNOPSIS
#include <ncursesw/curses.h>
int bkgrnd( const cchar_t *wch);
int wbkgrnd( WINDOW *win, const cchar_t *wch);
void bkgrndset(const cchar_t *wch );
void wbkgrndset(WINDOW *win, const cchar_t *wch);
int getbkgrnd(cchar_t *wch);
int wgetbkgrnd(WINDOW *win, cchar_t *wch);
DESCRIPTION
bkgrndset
The bkgrndset and wbkgrndset routines manipulate the background of the
named window. The window background is a cchar_t consisting of any
combination of attributes (i.e., rendition) and a complex character.
The attribute part of the background is combined (OR'ed) 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 charac‐
ter 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.
bkgrnd
The bkgrnd and wbkgrnd functions set the background property of the
current or specified window and then apply this setting to every char‐
acter position in that window:
· The rendition of every character on the screen is changed to the
new background rendition.
· Wherever the former background character appears, it is changed to
the new background character.
getbkgrnd
The getbkgrnd function returns the given window's current background
character/attribute pair via the wch pointer. If the given window
pointer is null, the character is not updated (but no error returned).
ATTRIBUTES
See attributes(7) for descriptions of the following attributes:
box; cbp-1 | cbp-1 l | l . ATTRIBUTE TYPE ATTRIBUTE VALUE = Availabil‐
ity library/ncurses = Stability Uncommitted
NOTES
Note that bkgrnd, bkgrndset, and getbkgrnd may be macros.
X/Open Curses does not provide details on how the rendition is changed.
This implementation follows the approach used in SVr4 curses, which is
explained in the manual page for wbkgd.

This software was built from source available at

RETURN VALUE
The bkgrndset and wbkgrndset routines do not return a value.
Upon successful completion, the other functions return OK. Otherwise,
they return ERR:
· A null window pointer is treated as an error.
· A null character pointer is treated as an error.
PORTABILITY
These functions are described in the XSI Curses standard, Issue 4
(X/Open Curses).
