RETURN VALUE

-       These functions are described in the XSI Curses standard, Issue 4.   It
-       specifies  that  bkgd  and  wbkgd  return  ERR on failure, but gives no
-       failure conditions.
-
-       The routines bkgd and wbkgd return the integer OK, unless  the  library
-       has not been initialized.
+       Functions returning an int return OK on success.  bkgd returns  ERR  if
+       the  library has not been initialized.  wbkgd and getbkgd return ERR if
+       the WINDOW pointer argument is null.
 
-       In  contrast, the SVr4.0 manual says bkgd and wbkgd may return OK "or a
-       non-negative integer if immedok is set", which  refers  to  the  return
-       value  from wrefresh (used to implement the immediate repainting).  The
-       SVr4 curses wrefresh returns the number of characters  written  to  the
-       screen during the refresh.  This implementation does not do that.

NOTES

+       Unusually, there is no wgetbkgd function; getbkgd behaves as one  would
+       expect wgetbkgd to, accepting a WINDOW pointer argument.

        Note that bkgdset and bkgd may be macros.
 
        X/Open  Curses  mentions that the character part of the background must
-       be a single-byte value.  This  implementation,  like  SVr4,  checks  to
