.SH DESCRIPTION
.sp
.LP
The \fBcopywin()\fR function provides a finer granularity of control over the
\fBoverlay\fR(3XCURSES) and \fBoverwrite\fR(3XCURSES) functions. As in the
\fBprefresh()\fR function (see \fBnewpad\fR(3XCURSES)), a rectangle is
specified in the destination window, (\fIdminrow\fR, \fIdmincol\fR) and
(\fIdmaxrow\fR, \fIdmaxcol\fR), and the upper-left-corner coordinates of the
source window, (\fIsmincol\fR, \fIsminrow\fR). If \fIoverlay\fR is \fBTRUE\fR,
then copying is non-destructive, as in \fBoverlay()\fR. If \fIoverlay\fR is
\fBFALSE\fR, then copying is destructive, as in \fBoverwrite()\fR.
.SH RETURN VALUES
.sp
.LP
Upon successful completion, the \fBcopywin()\fR function returns \fBOK\fR.
Otherwise, it returns \fBERR\fR.
.SH ERRORS

No errors are defined.
