ILMDVRSink *pILMDVRSink ;	/* pointer to an interface */
BSTR pszTargetFile;	/* pointer to the target file */
double startOffset;	/* starting offset */
double endOffset;	/* ending offset */

Copies the buffered recording data to the specified fully qualified target file pathname.

Parameter	Description
pILMDVRSink	Pointer to an ILMDVRSink interface.
pszTargetFile	Pointer to a fully qualified destination file.
startOffset	Starting offset of data to copy.
endOffset	Ending offset of data to copy.

Returns

S_OK	The function was successful.
<> S_OK	An error occurred. Refer to the Error Codes or the HRESULT error codes in the DirectShow documentation.
