The SetGlobalParam method sets global values for the performance.
HRESULT SetGlobalParam( REFGUID rguidType, void* pParam, DWORD dwSize );
Reference to (C++) or address of (C) the identifier of the type of data.
Address of data to be copied and stored by the performance.
Size of the data. This is constant for each rguidType.
If the method succeeds, the return value is S_OK.
If it fails, the method can return one of the error values shown in the following table.
The dwSize parameter is needed because the performance does not know about all types of data. New types can be created as needed.
For the parameters defined by DirectMusic and their associated data types, see Setting and Retrieving Global Parameters.
