.SH DESCRIPTION
.sp
.LP
The \fBattr_get()\fR function retrieves the current rendition of \fIstdscr\fR.
The \fBwattr_get()\fR function retrieves the current rendition of window
\fIwin\fR.  If \fIattrs\fR or \fIcolor\fR is a null pointer, no information is
retrieved.
.sp
.LP
The \fBattr_off()\fR and \fBattr_on()\fR functions unset and set,
respectively, the specified window attributes of \fBstdscr\fR.  These functions
only affect the attributes specified; attributes that existed before the call
are retained.
.sp
.LP
The \fBwattr_off()\fR and \fBwattr_on()\fR functions unset or set the
specified attributes for window \fIwin\fR.
.sp
.LP
The \fBattr_set()\fR and \fBwattr_set()\fR functions change the rendition of
\fBstdscr\fR and \fIwin\fR; the old values are not retained.
.sp
.LP
The \fBcolor_set()\fR and \fBwcolor_set()\fR functions set the window color of
\fBstdscr\fR and \fIwin\fR to \fIcolor\fR.
.sp
.LP
The attributes and color pairs that can be used are specified in the
\fBAttributes, Color Pairs, and Renditions\fR section of the
\fBcurses\fR(3XCURSES) man page.
