The GetTime method retrieves the current reference time. This method implements the IReferenceClock::GetTime method.
Syntax
HRESULT GetTime(
REFERENCE_TIME *pTime
);
Parameters
pTime
Pointer to a variable that receives the current time, in 100-nanosecond units.
Return Value
Returns one of the HRESULT values shown in the following table.
| Value | Description |
| E_POINTER | NULL pointer argument. |
| S_FALSE | Returned time is the same as the previous value. |
| S_OK | Success. |
Remarks
This method calls the CBaseReferenceClock::GetPrivateTime method to determine the real clock time. If the clock time is strictly greater than the previous value, GetTime uses the clock time and returns S_OK. Otherwise, GetTime uses the previous value and returns S_FALSE. Therefore, the internal clock can run backward for a short period, without causing the reference time to run backward. Instead, the reference time will "stall" at the same value until the internal clock catches up.
