ICM_DRAW_START  1FBPA2N 

The ICM_DRAW_START message notifies a rendering driver to start its internal clock for the timing of drawing frames. You can send this message explicitly or by using the ICDrawStartD3RBL2 macro.

ICM_DRAW_START

wParam = 0;

lParam = 0;

 

Return Values

This message does not return a value.

Remarks

This message is used by hardware that performs its own asynchronous decompression, timing, and drawing.

When the driver receives this message, it should start rendering data at the rate specified with the ICM_DRAW_BEGIN33JT_2P message.

The ICM_DRAW_START and ICM_DRAW_STOP messages do not nest. If your driver receives ICM_DRAW_START before rendering is stopped with ICM_DRAW_STOP, it should restart rendering with new parameters.
