CBaseReferenceClock.GetTime method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
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.
Return code | Description |
---|---|
|
NULL pointer argument. |
|
Returned time is the same as the previous value. |
|
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.
