Really solid advice throughout. If you're using non-POD C++ and want to allow custom allocators (wise), I would keep it simple and use placement new instead of messing about with per-class operator new. If you must you can wrap it up in little internal template functions to make it a little more palatable. Eg: template <typename T> T *yl_new(Context *context) { return new(context->malloc(sizeof(T)) T(); } template <typename T> void yl_delete(Context *context, T *object) { object->~T(); context->free(object); }
