|
||||

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

||||
void wbkgrndset(WINDOW *win, const cchar_t *wch);
|
||||
int wgetbkgrnd(WINDOW *win, cchar_t *wch);
|
||||
|
||||
Description:
|
||||
bkgdset() and wbkgdset() manipulate the background of a window.
|
||||
The background is a chtype consisting of any combination of
|
||||
attributes and a character; it is combined with each chtype
|
||||
added or inserted to the window by waddch() or winsch(). Only
|
||||
the attribute part is used to set the background of non-blank
|
||||
characters, while both character and attributes are used for
|
||||
blank positions.
|
||||
|
||||
bkgd() and wbkgd() not only change the background, but apply it
|
||||
immediately to every cell in the window.
|
||||
|
||||
The attributes that are defined with the attrset()/attron() set
|
||||
of functions take precedence over the background attributes if
|
||||
there is a conflict (e.g., different color pairs).
|
||||
|
||||
Return Value:
|
||||
bkgd() and wbkgd() return OK, unless the window is NULL, in
|
||||
which case they return ERR.
