The code:

template <class T, class C, T (C::*g)(), bool (C::*s)(T), class dummy = void>
class pmfu;

template <class T, class C, T (C::*g)(), bool (C::*s)(T)>
class pmfu<T,C,g,s,typename std::enable_if<g != nullptr && s == nullptr>::type> 
  {
  public:
  explicit pmfu(C & c) { }
  };

template<typename T>
struct pmfu_d
  {
  pmfu_d() : gl_r() { }
  T gl_r;
  T gl_fun_r_read() { return gl_r; }
  };

pmfu_d<char> data_inst_char;

pmfu<char,
     pmfu_d<char>,
     &pmfu_d<char>::gl_fun_r_read,
     nullptr> 
pf_read_ch(data_inst_char);

int main() { return 0; }
