.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.
|
|
|
|
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 functions
|
|
set the background property of the current or specified window
|
|
and then apply this setting to every character position in that window:
|
|
|
|
.RS
|
|
The rendition of every character on the screen is changed to
|
|
the new background rendition.
|
|
|
|
Wherever the former background character
|
|
appears, it is changed to the new background character.
|
|
.RE
|
|
|
|
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. The draft
|
|
does not include \fBconst\fR qualifiers on the arguments. The standard
|
|
specifies that \fBbkgd\fR and \fBwbkgd\fR return \fBERR\fR, on failure. but
|
|
gives no failure conditions.
