Defined in header <meta>
consteval bool is_member_function_pointer_type( std::meta::info r );		(since C++26)

Returns true if r represents a type that is a pointer to a non-static member function. Otherwise returns false.

Parameters

r

-

a reflection value

Return value

true if r represents a member function pointer type; otherwise false.

Exceptions

Throws std::meta::exception if r does not represent a type or type alias.

Example

Run this code

#include <meta>

struct A
{
    int m;
    inline static int n{};
    void f() {}
    static void g();
};

int main()
{
    int A::*mem_data_ptr = &A::m;     // a pointer to member data
    int* data_ptr = &A::n;            // a pointer to static member data
    void (A::*mem_fun_ptr)() = &A::f; // a pointer to member function
    void (*fun_ptr)() = &A::g;        // a pointer to static member function

    static_assert
    (""
        &&   is_member_function_pointer_type(^^decltype(mem_fun_ptr))
        && ! is_member_function_pointer_type(^^decltype(fun_ptr))
        && ! is_member_function_pointer_type(^^decltype(mem_data_ptr))
        && ! is_member_function_pointer_type(^^decltype(data_ptr))
        && ! is_member_function_pointer_type(^^int (*)())
        && ! is_member_function_pointer_type(^^A const* volatile)
    );
