NAME
       bkgrnd,  wbkgrnd,  bkgrndset,  wbkgrndset,  getbkgrnd,  wgetbkgrnd - curses window complex
       background manipulation routines

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);

DESCRIPTION
       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., rendi-
       tion) 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 character 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.

       The  bkgrnd  and wbkgrnd functions set the background property of the current or specified
       window and then apply this setting to every character 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 back-
              ground character.

       The getbkgrnd function returns the given window's current  background  character/attribute
       pair via the wch pointer.

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

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.
