Where would one look to find an "extern"?

If one were to view a decompilation of Unity in search of one function’s implementation?

And only found this:

    [GeneratedByOldBindingsGenerator]
    [MethodImpl(MethodImplOptions.InternalCall)]
    public static extern float[] GetMinMaxData(AudioImporter importer);

Where would one go from there?

You find it in the native code of the Unity engine which you can’t decompile. In other words you can’t dig any deeper. The actual code for that method has been written in C++. The method is defined inside the Unity.exe itself. The original location is most likely in a file called “AudioUtilBindings.gen.cpp” which however is of course not shipped with Untiy as Unity is a closed source application.
