NAME    [Toc]    [Back]

     fullscrn -	allows a program write to the entire screen

C SPECIFICATION    [Toc]    [Back]

     void fullscrn()

PARAMETERS    [Toc]    [Back]

     none

DESCRIPTION    [Toc]    [Back]

     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(GD_XPMAX)-1, 0, getgdesc(GD_YPMAX)-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.

NOTES    [Toc]    [Back]

     This routine is available only in immediate mode.

     Use fullscrn with caution or a sense of humor.
