The IDirectMusicTool::GetMediaTypeArraySize method retrieves the size of the array that must be passed in to the IDirectMusicTool::GetMediaTypes method. A return value of 0 indicates that the tool handles all types, and it is unnecessary to call GetMediaTypes.
HRESULT GetMediaTypeArraySize( DWORD* pdwNumElements );
Return values are determined by the implementation. If the method succeeds, it returns S_OK. If it fails, the method can return E_POINTER.
