This `struct` template implements the `is_member_function_pointer` meta‐function defined in the C++11 standard [meta.unary.cat]to determine if the (template parameter) `t_TYPE` is a pointer to non‐static member function type. This `struct` derives from `bsl::true_type` if the `t_TYPE` is a pointer to non‐static member function type, and from `bsl::false_type` otherwise. Additional specializations are provided below to give the correct answer in all cases.
