HRESULT Info( AVISTREAMINFOW *psi, LONG lSize );
Pointer to an AVISTREAMINFO structure to contain stream information.
Size, in bytes, of the structure specified by psi.
Returns the HRESULT defined by OLE.
If the buffer allocated is too small for the structure, the Info method should fail the call by returning AVIERR_BUFFERTOOSMALL. Otherwise, it should fill the structure and return its size.
For handlers written in C++, Info has the following syntax:
HRESULT Info(AVIFILEINFO *psi, LONG lSize)
