.SH DESCRIPTION
.sp
.LP
The \fBinsdelln()\fR and \fBwinsdelln()\fR functions insert or delete blank
lines  in \fBstdscr\fR or \fIwin\fR, respectively.  When \fIn\fR is positive,
\fIn\fR lines are added before the current line  and the bottom \fIn\fR lines
are lost; when \fIn\fR is negative, \fIn\fR lines  are deleted starting with
the current line, the remaining lines are moved up,  and the bottom \fIn\fR
lines are cleared. The position of the cursor does not change.
.SH RETURN VALUES
