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. +It specifies that \fBbkgd\fR and \fBwbkgd\fR return \fBERR\fR on failure. +but gives no failure conditions. +.SH SEE ALSO +\fBcurses\fR(3X), +\fBcurs_addch\fR(3X), +\fBcurs_attr\fR(3X), +\fBcurs_outopts\fR(3X) +.\"# +.\"# The following sets edit modes for GNU EMACS +.\"# Local Variables: +.\"# mode:nroff +.\"# fill-column:79 +.\"# End: |
