.SH DESCRIPTION
.sp
.LP
These functions change the renditions of the next \fIn\fR characters in the
current or specified window (or of the remaining characters on the current or
specified line, if \fIn\fR is \(mi1), beginning at the current or specified
cursor position. The attributes and colors are specified by \fIattr\fR and
\fIcolor\fR as for \fBsetcchar\fR(3XCURSES).
.sp
.LP
These function neither update the cursor nor perform wrapping.
.sp
.LP
A value of \fIn\fR that is greater than the remaining characters on a line is
not an error.
.sp
.LP
The \fIopts\fR argument is reserved for definition in a future release.
Currently, the application must provide a null pointer for \fIopts\fR.
