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.

Comments

Whenever data is written to a buffer file, the windows event for the returned write event handle will be set.

Likewise, when a buffer file is created or closed, the windows event for the list changed event handle will be set.

Also, when data is written past the offset indicated by ILMDVRSink::SetOffsetToReach method, the offset reached event is set.

Returns S_OK if successful, otherwise a return code indicating the reason for failure:

E_OUTOFMEMORY = Memory allocation error was encountered.
