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
