Hi, I'm having a problem in pass a function as argument to another function.
This call is made by reference, and the function called is declared into a class.
A example of my problem is:

Code:
class ExClass {
       public:
             int func(const int &); //***
};

int ExClass::func(const int &z) { return(z); }

template <class T>
void example(T &func) {}

int main(){
     ExClass f;
     example( f.func );
     return(0);
}
When I compile that, I got such error:

In function ‘int main()’:
error: no matching function for call to ‘example(<unresolved overloaded function type>)’
note: candidates are: void example(T&) [with T = int (ExClass::*)(const int&)]


*** It's good to mention that if I declared "func" as "static int func(const int &);" into the "ExClass", I get no error. But I need let "func" be non-static.

What am I supposed to do?
Thank you.
