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

This function was added for languages like FoxPro that will not query for the dispatch interface itself.

If the function succeeds, the user should release the retrieved interface pointer by calling the interfaces Release method.
