bkgd(3XCURSES) X/Open Curses Library Functions bkgd(3XCURSES) NAME bkgd, bkgdset, getbkgd, wbkgd, wbkgdset - set or get the background character (and rendition) of window 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 bkgd(chtype ch); void bkgdset(chtype ch); chtype getbkgd(WINDOW *win); int wbkgd(WINDOW *win, chtype ch); void wbkgdset(WINDOW *win, chtype ch); DESCRIPTION The bkgdset() and wbkgdset() functions turn off the previous background attributes, logical OR the requested attributes into the window rendi- tion, and set the background property of the current or specified win- dow based on the information in ch. If ch refers to a multi-column character, the results are undefined. The bkgd() and wbkgd() functions turn off the previous background at- tributes, logical OR the requested attributes into the window rendi- tion, and set the background property of the current or specified win- dow 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. The getbkgd() function extracts the specified window's background char- acter and rendition. PARAMETERS ch Is the background character to be set. win Is a pointer to the window in which the background character is to be set. RETURN VALUES Upon successful completion, the bkgd() and wbkgd() functions return OK. Otherwise, they return ERR. The bkgdset() and wbkgdset() functions do not return a value. Upon successful completion, the getbkgd() function returns the speci- fied window's background character and rendition. Otherwise, it returns (chtype)ERR. ERRORS No errors are defined. USAGE These functions are only guaranteed to operate reliably on character sets in which each character fits into a single byte, whose attributes can be expressed using only constants with the A_ prefix.
