+.SH DESCRIPTION
+The \fBbkgrndset\fR and \fBwbkgrndset\fR routines manipulate the
+background of the named window.
+The window background is a \fBcchar_t\fR consisting of
+any combination of attributes (i.e., rendition) 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 \fBwaddch\fR. 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.
+.PP
+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.
+.PP
+The \fBbkgrnd\fR and \fBwbkgrnd\fR functions
+set the background property of the current or specified window
+and then apply this setting to every character position in that window:
+.RS
+.PP
+The rendition of every character on the screen is changed to
+the new background rendition.
+.PP
+Wherever the former background character
+appears, it is changed to the new background character.
+.RE
+.PP
+The \fBgetbkgrnd\fR function returns the given window's current background
+character/attribute pair via the \fBwch\fR pointer.
+.
+.SH NOTES
+Note that
+\fBbkgrnd\fR,
+\fBbkgrndset\fR, and
+\fBgetbkgrnd\fR
+may be macros.
+.SH RETURN VALUES
+The \fBbkgrndset\fR and \fBwbkgrndset\fR routines do not return a value.
+.PP
+Upon successful completion, the other functions return \fBOK\fR.
+Otherwise, they return \fBERR\fR.
+A null window pointer is treated as an error.
