25<H2>Description</H2>
26<P>This is a synchronization function that calls the <a href="GXSetDrawDone.html"><code>GXSetDrawDone</code></a> and <a href="GXWaitDrawDone.html"><code>GXWaitDrawDone</code></a> functions in succession. As a result, it will wait (stall) until all graphics commands have executed and the last pixel is written to the frame buffer.&nbsp;This function flushes the write-gather FIFO in the CPU to&nbsp;make sure that all commands are sent to the graphics processor before the stall.</P>
27<P>The net effect is that this function will send a <em>DrawDone</em> command to the Graphics Processor, run the <code><a href="GXFlush.html">GXFlush</a></code> function, and wait until it has been run. There is no need to explicitly call the <A href="../Management/GXFlush.html"><CODE>GXFlush</CODE></A> function after you have executed <CODE>GXDrawDone</CODE>.</P></P>
28<P>This function should only be used in immediate-mode, as the command processor will continue to execute commands from the current FIFO.</P>
29<P>This function may put the current thread to sleep. For precautions when calling similar functions, refer to <A href="../../os/Interrupt/intro.html">Interrupts and Callback Functions</A>.</P>
