ICDrawSetTime
The ICDrawSetTime macro 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 use this macro or explicitly call the ICM_DRAW_SETTIME message.
DWORD ICDrawSetTime(
Parameters
hic
Handle of a driver.
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).
