Description
Implementation of invoke_result<t_FN, t_ARG1TYPE, t_ARGTYPES...>. This specialization is instantiated in C++11 and later when t_FN is a pointer-to-member-function type, t_ARG1TYPE is neither a class type that derives from the class type of t_FN nor a specialization of bsl::reference_wrapper, and the INVOKE(fn, arg1, args...) expression is well-formed given fn is an object of the specified t_FN type and arg1, args... are objects of the specified t_ARG1TYPE, t_ARGTYPES... types. The INVOKE(fn, arg1, args...) expression in this case is ((*arg1).*fn)(args...).
