IWMWriterFileSink::Open method

The Open method opens a file that acts as the writer sink.

Syntax

HRESULT Open(
  const WCHAR *pwszFilename
);

pwszFilename

Pointer to a wide-character null-terminated string containing the file name. URLs are not supported.

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_POINTER	The pwszFilename parameter is NULL.

There is no close method in this interface as the closing of the writer sink file is done automatically by a call to IWMWriter::EndWriting.
