  Functions
template<typename _Ret , typename _Tp , typename _Arg > mem_fun1_t< _Ret, _Tp, _Arg > std::mem_fun (_Ret(_Tp::*__f)(_Arg))
template<typename _Ret , typename _Tp > mem_fun_t< _Ret, _Tp > std::mem_fun (_Ret(_Tp::*__f)())
template<typename _Ret , typename _Tp , typename _Arg > mem_fun1_ref_t< _Ret, _Tp, _Arg > std::mem_fun_ref (_Ret(_Tp::*__f)(_Arg))
template<typename _Ret , typename _Tp > mem_fun_ref_t< _Ret, _Tp > std::mem_fun_ref (_Ret(_Tp::*__f)())

Detailed Description

There are a total of 8 = 2^3 function objects in this family. (1) Member functions taking no arguments vs member functions taking one argument. (2) Call through pointer vs call through reference. (3) Const vs non-const member function.

All of this complexity is in the function objects themselves. You can ignore it by using the helper function mem_fun and mem_fun_ref, which create whichever type of adaptor is appropriate.
