fullscrn(3G) — IRIX 6.5.3f



fullscrn(3G)                                                      fullscrn(3G)



NAME
     fullscrn - allows a program write to the entire screen

C SPECIFICATION
     void fullscrn()

PARAMETERS
     none

DESCRIPTION
     fullscrn allows a program write to the entire screen.  It does this by
     eliminating the protections that normally prevent a graphics process from
     drawing outside of its current window.  fullscrn calls
     viewport(0, getgdesc(GDXPMAX)-1, 0, getgdesc(GDYPMAX)-1) and ortho2 to
     set up an orthographic projection that maps world coordinates to screen
     coordinates.  The current viewport and matrix state are not saved; it is
     the caller's responsibility to do this.

     fullscrn only affects graphics output; input focus management is
     unchanged.

     This routine is available only in immediate mode.

     Use fullscrn with caution or a sense of humor.
