IWMWriter::EndWriting 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 It has been superseded by Source Reader and Sink Writer.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 EndWriting method performs tasks required at the end of a writing session. This method flushes the buffers, updates indices and headers, and closes the file. You must call EndWriting when you have finished sending samples to the writer to encode an ASF file.
Syntax
HRESULT EndWriting();
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. |
|
The writer cannot currently be run. |
Remarks
This method will not return a failure code if the disk space was used up before the encoding was completed. In order to be notified of a file writing error, an application should implement the IWMStatusCallback method and listen for the NS_E_FILE_WRITE event.
