NAME

bkgrnd, bkgrndset, getbkgrnd, wbkgrnd, wbkgrndset, wgetbkgrnd - set or get the background character (and rendition) of window using a complex character
 

SYNOPSIS

cc [ flag... ] file... -I /usr/xpg4/include  -L  /usr/xpg4/lib \
 -R  /usr/xpg4/lib  -lcurses  [ library... ]

c89 [ flag... ] file... -lcurses [ library... ]

#include <curses.h>

int bkgrnd(const cchar_t *wch);

void bkgrndset(const cchar_t *wch);

int getbkgrnd(cchar_t *wch);

int wbkgrnd(WINDOW *win, const cchar_t *wch);

void wbkgrndset(WINDOW *win, const cchar_t *wch);

int wgetbkgrnd(WINDOW *win, cchar_t *wch);

DESCRIPTION

The bkgrndset() and wbkgrndset() functions turn off the previous background attributes, logical OR the requested attributes into the window rendition, and set the background property of the current or specified window based on the information in wch.

The bkgrnd() and wbkgrnd() functions turn off the previous background attributes, logical OR the requested attributes into the window rendition, and set the background property of the current or specified window and then apply this setting to every character position in that window:

o The rendition of every character on the screen is changed to the new window rendition.

o Wherever the former background character appears, it is changed to the new background character.

If wch refers to a non-spacing complex character for bkgrnd(), bkgrndset(), wbkgrnd(), and wbkgrndset(), then wch is added to the existing spacing complex character that is the background character. If wch refers to a multi-column character, the results are unspecified.

The getbkgrnd() and wgetbkgrnd() functions store, into the area pointed to buy wch, the window's background character and rendition.  

PARAMETERS

wch

Is a pointer to the complex background character to be set.

win

Is a pointer to the window in which the complex background character is to be set.

RETURN VALUES

The bkgrndset() and wbkgrndset() functions do not return a value.

Upon successful completion, the other functions return OK. Otherwise, they return ERR.  

ERRORS

No errors are defined.
