c++11 - alias for multi parameter function template

itemprop="text">

I am trying to create a template for a
multi-parameter function, and then an alias for a particular instantiation. From this
really good post:

href="https://stackoverflow.com/questions/9864125/c11-how-to-alias-a-function">C++11:
How to alias a function?

I
found example code that works for a single function parameter and single template
parameter:

#include
            
namespace Bar
{
 void test()

            {
 std::cout << "Test\n";
 }



            template
 void test2(T const& a)
 {

            std::cout << "Test: " << a << std::endl;

            }
}

void (&alias)() = Bar::test;
void
            (&a2)(int const&) = Bar::test2;


int
            main()
{
 Bar::test();
 alias();

            a2(3);
}

When
I try to expand to two function parameters as
such:

void noBarTest(T
            const& a, T const& b)
{
 std::cout << "noBarTest: "
            << a << std::endl;
}

void(&hh)(int
            const&, int const&) = noBarTest            int>;

I get these
errors in Visual
Studio:

error C2440: 'initializing' : cannot convert from 'void (__cdecl

*)(const T &,const T &)' to 'void (__cdecl &)(const int &,const int
&)'

IntelliSense: a reference of type
"void (&)(const int &, const int &)"
(not const-qualified) cannot
be initialized with a value of type

""

I
thought I followed the pattern exactly in expanding to 2 arguments.
What's
the proper syntax for this?

template             T>
void noBarTest(T const& a, T const&
            b)
{
}

void(&hh)(int const&, int
            const&) = noBarTest; // Only once

int main()
            {

 return
            0;
}

The
type parameter int needs to be specified only once in
noBarTest.
