Callback function



when using the API from Unmanaged C++ through COM interaction, where the client application is totally unaware about .NET delegates, you should use the "Ptr" version of the method which allows passing the pointer to the callback function:


[Unmanaged C++]

enumErrorCodes CallbackWaveAnalyzerSpectralViewDoneSetPtr (

(UINT_PTR) functionPointer








Pointer to the callback function.

See the Adding the API to an unmanaged Visual C++ project tutorial for details about usage of the "Ptr" version of these methods.
