+.SH DESCRIPTION
+.sp
+.LP
+The \fBtouchwin()\fR and \fBtouchline()\fR routines throw away all optimization
+information about which parts of the window have been touched, by pretending
+that the entire window has been drawn on. This is sometimes necessary when
+using overlapping windows, since a change to one window affects the other
+window, but the records of which lines have been changed in the other window do
+not reflect the change. The routine \fBtouchline()\fR only pretends that
+\fIcount\fR lines have been changed, beginning with line \fIstart\fR.
+.sp
+.LP
+The \fBuntouchwin()\fR routine marks all lines in the window as unchanged since
+the last call to \fBwrefresh()\fR.
+.sp
+.LP
+ The \fBwtouchln()\fR routine makes \fIn\fR lines in the window, starting at
+line \fIy\fR, look as if they have (\fIchanged\fR\fB=1\fR) or have not
+(\fIchanged\fR\fB=0\fR) been changed since the last call to \fBwrefresh()\fR.
+.sp
+.LP
+The \fBis_linetouched()\fR and \fBis_wintouched()\fR routines return \fBTRUE\fR
+if the specified line/window was modified since the last call to
+\fBwrefresh()\fR; otherwise they return \fBFALSE\fR. In addition,
+\fBis_linetouched()\fR returns \fBERR\fR if \fBline\fR is not valid for the
+given window.
+.SH RETURN VALUES
+.sp
+.LP
+All routines return the integer \fBERR\fR upon failure and an integer value
+other than \fBERR\fR upon successful completion, unless otherwise noted in the
+preceding routine descriptions.
