NAME

cursoff − turns off the cursor

SPECIFICATION

C
cursoff()

FORTRAN
subroutine cursof

Pascal
procedure cursoff;

DESCRIPTION

cursoff turns off the cursor so that it is no longer visible.  cursoff should precede drawing routines that write into the currently displayed cursor bitplanes. 

The cursor is always displayed by default.  Before the cursor is drawn on the screen, the IRIS saves the image that the cursor covers.  When the cursor moves, the system restores the saved image.  If the image changes while the cursor is displayed, the saved image may no longer be valid.  This is a concern in single buffer and RGB modes, and in double buffer mode when the front buffer is enabled.
