.SH DESCRIPTION
.sp
.LP
The \fBmvderwin()\fR function defines a mapped area of \fIwin\fR's parent
window that is the same size as \fIwin\fR and has its upper left corner at
position \fIpar_y\fR, \fIpar_x\fR of the parent window.
.sp
.LP
Whenever \fIwin\fR is refreshed, its contents are updated to match those of the
mapped area and any reference to characters in \fIwin\fR is treated as a
reference to corresponding characters in the mapped area.
.SH RETURN VALUES
.sp
.LP
On success, the \fBmvderwin()\fR function returns \fBOK\fR. Otherwise, it
returns \fBERR\fR.
.SH ERRORS
.sp
.LP
None.
