34<H2>Description</H2>
35<P>This function registers a callback that is called when a <EM>DrawDone</EM> command appears in the Graphics Processor.&nbsp;The <EM>DrawDone</EM> command is set by the <A href="GXSetDrawDone.html"><CODE>GXSetDrawDone</CODE></A> function.&nbsp;<BR><BR><B>Note:</B> By the time the callback is invoked, the Graphics Processor will already have resumed reading from the command FIFO, if there are any commands in it.<BR></P>
36<P>The callback will be invoked with interrupts disabled, so it is imperative that it return as quickly as possible.&nbsp;</P>
37<P>You can also use <a href="GXWaitDrawDone.html"><code>GXWaitDrawDone</code></a> to block your application until this event occurs.</P>
