wParam = (DWORD) (LPVOID) lplTime;
lParam = 0;

Requests a rendering driver that controls the timing of drawing frames to return the current value of its internal clock.

• Returns ICERR_OK if successful or an errorr otherwise.

wParam

Address to contain the current time. The return value should be specified in samples.

This message is generally supported by hardware that performs its own asynchronous decompression, timing, and drawing. The message can also be sent if the hardware is being used as the synchronization master.
