Retrieves a vendor information string.
HRESULT QueryVendorInfo( LPWSTR * pVendorInfo );
Parameters
- pVendorInfo
- Pointer to a string containing vendor information.
Return Values
Returns an HRESULTvalue (E_NOTIMPL by default).
Remarks
This member function implements the IBaseFilter::QueryVendorInfomethod, but only to return E_NOTIMPL. Filters that want to expose vendor information must override this member function. If implemented in a derived class, callers should free memory when they are done using it by calling the Microsoft Win32 CoTaskMemFreefunction.
