◆ AK_WWISE_PLUGIN_DERIVE_FROM_BACKEND_INSTANCE

#define AK_WWISE_PLUGIN_DERIVE_FROM_BACKEND_INSTANCE ( x ) struct x : public ak_wwise_plugin_backend_instance {}

Define an instance type as a backend.

In C++, this derives the backend instance from the ak_wwise_plugin_backend_instance in a separate action so that RTTI can help pinpoint the types and the compiler ensures the type correctness.

In C, this is a typedef, as we cannot derive. The compiler also doesn't need to lookup addresses for complex structures, so this is merely an equivalency.
