Pointers to member functions are very strange animals Answer to exercise: Pointer to member function cast Member Function Pointers and the Fastest Possible C++ Delegates 更新(4/12/2012):研究了下FastDelegates的代码,针对VC,好像我的理解还是有点偏差。
A member function pointer for a non-virtual member function is represented with ptr set to a pointer to the function, using the base ABI's representation of function pointers. In the standard representation, a member function pointer for a virtual function is represented with ptr set to 1 plus...

std::is_member_function_pointer 是一元类型特征 (UnaryTypeTrait) 。 检查T 是否为非静态成员函数指针。如果 T 为非静态成员函数指针类型,那么提供的成员常量 value 等于true。否则,value 等于false。 如果程序添加了 std::is_member_function_pointer 或std::is_member_function_pointer_v 的特化,那么行为未...

You make your function pointer point to a function float some_func(int, char *) like this: my_func_ptr = some_func; When you want to invoke the function that you stored, you do this: (*my_func_ptr)(7, "Arbitrary String"); You are allowed to cast from one type of function ...
