+\fBgetbkgd\fR \- \fBcurses\fR window background manipulation routines
.SH SYNOPSIS
\fB#include <curses.h>\fR
-
+.PP
\fBvoid bkgdset(chtype ch);\fR
.br
\fBvoid wbkgdset(WINDOW *win, chtype ch);\fR
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.

.SH RETURN VALUE
Note that \fBbkgdset\fR and \fBbkgd\fR may be macros.
.SH PORTABILITY
These functions are described in the XSI Curses standard, Issue 4.
-It specifies that \fBbkgd\fR and \fBwbkgd\fR return \fBERR\fR on failure.
+It specifies that \fBbkgd\fR and \fBwbkgd\fR return \fBERR\fR on failure,
but gives no failure conditions.
