.SH Description
.NXR "leaveok subroutine"
This option allows the cursor to be left 
wherever the update happens to leave it.
Normally, the cursor is left at the 
current location (y, x) of the window 
being refreshed.
This routine is useful for applications where the cursor is not used, 
since it reduces the need for cursor motions.
If possible, the cursor is made invisible when this option is enabled.
.PP
This option is initially disabled, and is not enabled until the value of 
.PN bf
is changed from 
.PN FALSE
to
.PN TRUE .
.SH Return Values
The 
.PN leaveok
function returns OK on success and ERR on error.
