.SH Description
.NXR "touchwin subroutine"
This routine discards all optimization information
for the specified window and assumes
that the entire window has been drawn on.

This is sometimes necessary when using overlapping windows,
as a change to one window will affect the other window.
The records of which lines have
been changed may not be correct for the window which has
not been changed directly.

.PN touchwin
function returns OK on success and ERR on error.
