ICDrawStart
The ICDrawStart macro notifies a rendering driver to start its internal clock for the timing
of drawing frames. You can use this macro or explicitly call the ICM_DRAW_START message.
DWORD ICDrawStart(
Parameters
hic
Handle of a driver.
Return Values
This macro 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_BEGIN message.
The ICDrawStart and ICDrawStop macros do not nest. If your driver receives ICDrawStart before rendering is stopped with ICDrawStop, it should restart rendering with new parameters.
