Alternative way to using mem_fun1() have been removed in Visual C++ 2015

Function mem_fun1() have been removed in VC++ 2015. Therefore I change my code to using mem_fun1_t() from:

mem_fun1(&classA::functA)

To:

mem_fun1_t<bool,classA,classB>(&classA::functA)

With declare of function functA():

bool classA::functA(classB x);

Is this correct?

The old member function adaptors are strictly superseded by std::mem_fn. Use that, not deprecated functions that are removed in C++17 (and will likely be removed from later versions of VS).

As to mem_fun1, that's never been in the standard. The standard had four mem_fun overloads to handle const and non-const member function pointers with either 0 or 1 arguments.
