IWMWriterAdvanced::GetWriterTime method (wmsdkidl.h)
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The GetWriterTime method retrieves the clock time that the writer is working to.
Syntax
HRESULT GetWriterTime(
[out] QWORD *pcnsCurrentTime
);
Parameters
[out] pcnsCurrentTime
Pointer to a variable containing the current time in 100-nanosecond units.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
pcnsCurrentTime is NULL. |
Remarks
This method returns the largest time stamp that the writer can currently process. This time stamp will increase as data is produced by the writer. This method can be used to ensure that data is delivered to the writer at the proper rate.
The time returned is the number of 100-nanosecond units since the call to IWMWriter::BeginWriting.
The writer can be running in real time. Call the IWMWriterAdvanced::IsRealTime method to ascertain whether this is true.
