fullscrn() — Silicon Graphics

NAME

fullscrn − enables the entire screen for writing in the window manager

SPECIFICATION

C
fullscrn()

FORTRAN
subroutine fullsc()

Pascal
procedure fullscrn;

DESCRIPTION

fullscrn enables the entire screen for writing in the window manager. It makes the call:

viewport(0,XMAXSCREEN,0,YMAXSCREEN);

and sets up the default ortho, which ginit defines. scrmask and viewport are issued with respect to the physical screen origin, not the origin of the graphics port. fullscrn eliminates all protections that prevent graphics processes from scribbling on each other. Use it with caution or a sense of humor.
