IWMWriterFileSink3::CompleteOperations 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 It has been superseded by Source Reader and Sink Writer.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 CompleteOperations method stops the writer sink after completing all operations in progress. This method is used with unbuffered I/O.

Syntax

HRESULT CompleteOperations();

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Remarks

This method is called when writes are performed as a result of calls to IWMWriterSink::OnHeader, IWMWriterSink::OnDataUnit, and IWMWriterFileSink3::OnDataUnitEx. Applications do not call this method.
