Posts: 5,409. Grill marks have been discussed many times over the years. Sure, they are pretty and make a really strong statement about the meat, but many high-dollar restaurants reportedly draw their grill marks on with a meat-marker, while others brush on a coat of sugar water prior to it hitting the hit grill.
Pointers to member functions in C++. This is how C++ uses function pointers when dealing with member functions of classes or structs. These are invoked using an object pointer or a this call. They are type safe in that you can only call members of that class (or derivatives) using a pointer of that type.
Asynchronous Callbacks. Delegates can also be used as CallBacks. CallBacks are used in many Windows API calls. You pass in a function pointer to the API call. When the API call gets finished with it's job, it then âcalls backâ to the function via the function pointer you passed it. This allows your code to know when the API call is done.
