HRESULT ToFileTime(PQWORD pqWord, FILETIME *pFT);

pqWord
[in] Address of a variable that contains the time, in bytes, that was returned by the engine.
pFT
[out] Address of a FILETIME structure that receives the time.
An application can use the value returned by ToFileTime to correlate real-time events with a time value returned by the engine. The value returned by the engine is an estimate that should be accurate to within a few seconds of the present time, but becomes less accurate further away from the present due to time variations in the audio card's clock.
