The "pointer to member" is distinct from the type "pionter", that is, a pointer to member is declared only by the pointer to member declarator syntax, and never by the pointer declarator syntax. There is no "reference-to-member" type in c++....
pointet to member-pointer 就是指向指针成员的成员指针，不要望文生义。
n; // pointer to the int that is a member of sPointers may appear as operands to the built-in indirection operator (unary operator*), which returns the lvalue expression identifying the pointed-to object: int n; int* p = &n; // pointer to n int& r = *p; // reference is bound...

std::is_member_pointer 是一元类型特征 (UnaryTypeTrait) 。 如果T 为指向非静态成员对象或非静态成员函数的指针,那么提供的成员常量 value 等于true。对于其它任何类型,value 等于false。 如果程序添加了 std::is_member_pointer 或std::is_member_pointer_v 的特化,那么行为未定义。

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...
