NAME
       curs_bkgrnd,  bkgrnd,  wbkgrnd, bkgrndset, wbkgrndset, getbkgrnd, wget‐
       bkgrnd - Set or get background character and rendition by using a  com‐

SYNOPSIS
       #include <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 );

LIBRARY

DESCRIPTION
       By using the information in wch, the bkgrndset and wbkgrndset functions
       set the background rendition and manipulate the window rendition of the
       current or specified window. These  functions  turn  off	 the  previous
       background attributes from the current window rendition and add the new
       background rendition from wch into the window rendition.

       The bkgrnd and wbkgrnd  functions  set  the  background	rendition  and
       manipulate  the	window	rendition  of the current or specified window.
       These functions turn off the previous background	 attributes  from  the
       current	window rendition and add the new background rendition from wch
       into the window rendition. They then apply this setting to every	 char‐
       acter  position in that window as follows: The rendition of every char‐
       acter on the screen is changed to the new window	 rendition.   Wherever
       the former background character appears, it is changed to the new back‐
       ground character.

       If wch refers to a nonspacing complex character for bkgrnd,  bkgrndset,
       wbkgrnd,	 or wbkgrndset, then wch is added to the existing spacing com‐
       plex character that is the background character. If  wch	 refers	 to  a
       multicolumn character, the results are unspecified.

       The  getbkgrnd  and wgetbkgrnd functions store into the area pointed to
       by wch the value of the window's background character and rendition.

NOTES
       The header file	<curses.h>  automatically  includes  the  header  file
       <stdio.h>.

       Note that bkgrnd, bkgrndset, and getbkgrnd may be macros.

RETURN VALUES
       The bkgrndset and wbkgrndset functions do not return a value.

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