+.SH NAME
+\fBbkgdset\fR, \fBwbkgdset\fR, \fBbkgd\fR,
+\fBwbkgd\fR - \fBncurses\fR window background manipulation routines
+.SH SYNOPSIS
+\fB#include <ncurses.h>\fR
+
+\fBvoid bkgdset(chtype ch);\fR
+.br
+\fBvoid wbkgdset(WINDOW *win, chtype ch);\fR
+.br
+\fBint bkgd(chtype ch);\fR
+.br
+\fBint wbkgd(WINDOW *win, chtype ch);\fR

+.SH DESCRIPTION
+The \fBbkgdset\fR and \fBwbkgdset\fR routines manipulate the
+background of the named window.  Background is a \fBchtype\fR
+consisting of any combination of attributes and a character.  The
+attribute part of the background is combined (ORed) 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.  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 \fBbkgd\fR and \fBwbkgd\fR routines combine the new background
+with every position in the window.  Background is any combination of
+attributes and a character.  Only the attribute part is used to set
+the background of non-blank characters, while both character and
+attributes are used for blank positions.  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.
+.SH RETURN VALUE
+\fBbkgd\fR and \fBwbkgd\fR return the integer \fBOK\fR, or a
+non-negative integer, if \fBimmedok\fR is set.
+.SH NOTES
+Note that \fBbkgdset\fR and \fBbkgd\fR may be macros.
+.SH BUGS
+\fBimmedok\fR is not yet implemented in ncurses 1.8.6.
