+.SH NAME
+\fBbkgdset\fR, \fBwbkgdset\fR,
+\fBbkgd\fR, \fBwbkgd\fR,
+\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
+.br
+\fBint bkgd(chtype ch);\fR

+\fBint wbkgd(WINDOW *win, chtype ch);\fR
+.br
+\fBchtype getbkgd(WINDOW *win);\fR
+.br
+.SH DESCRIPTION
+The \fBbkgdset\fR and \fBwbkgdset\fR routines manipulate the
+background of the named window.
+The window background is a \fBchtype\fR consisting of
+any combination of attributes (i.e., rendition) and a 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 \fBbkgd\fR and \fBwbkgd\fR functions
+set the background property of the current or specified window
+and then apply this setting to every character position in that window:
+.PP
+.RS
+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 \fBgetbkgd\fR function returns the given window's current background
+character/attribute pair.
+.SH RETURN VALUE
+The routines \fBbkgd\fR and \fBwbkgd\fR return the integer \fBOK\fR.
+The SVr4.0 manual says "or a non-negative integer if \fBimmedok\fR is set",
+but this appears to be an error.
+.SH NOTES
+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.
+but gives no failure conditions.
