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.
The type of the returned object has the following properties: 1  Its functional call returns the same as fn with its arguments bound to args... (or forwarded, for placeholders). 2  For (1), it may have a member result_type: if Fn is a pointer to function or member function type, it is defined as an alias of its return type.
