Description

This function waits until the hardware accelerator has completed all currently queued rendering operations. The primary purpose of this function is to provide the application with the ability to ensure all rendering is complete, before swapping display pages when doing double buffering, or before directly accessing the framebuffer memory.

Note: This function is required to wait for the entire graphics engine to be idle, including waiting until any pending DMA or bus master operations have completed.
