Returns: < 0 on error.

◆ sceGeDrawSync()

int sceGeDrawSync ( int syncType )

Wait for drawing to complete.

Parameters

syncType - 0 if you want to wait for the drawing to be completed, or 1 if you just want to peek the state of the display list currently being executed.

Returns: The current queue status, one of PspGeListState.

Referenced by sceGuSync().

◆ sceGeEdramGetAddr()
