3D Engine cast to pointer from integer of different size

[mor3245]

I've encountered this error message:
olcConsoleGameEngine.h:1198:18: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
1198 | ((olcConsoleGameEngine*)dwInstance)->waveOutProc(hWaveOut, uMsg, dwParam1, dwParam2);

Does anyone have a fix for this?

It is not an error message, is it?
