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.
Non-static member functions have a hidden parameter that corresponds to the this pointer. The this pointer points to the instance data for the object. The interrupt hardware/firmware in the system is not capable of providing the this pointer argument. You must use ânormalâ functions (non class members) or static member functions as interrupt service routines.
