NAME    [Toc]    [Back]

     ildraw - selects a	previously allocted ilbuffer as	the drawing
     destination

C SPECIFICATION    [Toc]    [Back]

     void ildraw(long buffer)

PARAMETERS    [Toc]    [Back]

     buffer   expects a	value from 1 to	the number of buffers returned by
	      ilbuffer(buffers);

DESCRIPTION    [Toc]    [Back]

     ildraw selects one	of the buffers previously allocated by ilbuffer	as the
     destination for drawing. Passing a	value of 0 deselects the buffer. The
     ilbuffers are screen-sized, and the coordinate system reflects this.
     Viewport should be	called after this routine to set the area of the
     screen sized buffer that is being used. Beware of programming errors in
     coordinate	systems	when copying to	or from	a windows front	and back
     buffers and the ilbuffer.

SEE ALSO    [Toc]    [Back]

     ilbuffer

NOTES    [Toc]    [Back]

     This subroutine is	available only in immediate mode and on	RealityEngine
     systems running 5.0.1 or later.
