ICM_DRAW_SETTIME
The ICM_DRAW_SETTIME provides synchronization information to a rendering
driver that handles the timing of drawing frames. The synchronization information is
the sample number of the frame to draw. You can send this message explicitly
or by using the ICDrawSetTime macro.
ICM_DRAW_SETTIME
wParam = (DWORD) lpTime;
lParam = 0;
Parameters
lpTime
Sample number of the frame to render.
Return Values
Returns ICERR_OK if successful or an error otherwise.
Remarks
Typically, the driver compares the specified value with the frame number
associated with the time of its internal clock and attempts to synchronize the two
if the difference is significant.
Use this message when the hardware performs its own asynchronous
decompression, timing, and drawing, and the hardware relies on an external synchronization
signal (the hardware is not being used as the synchronization master).
