How to cast overloaded free function to resolve overload conflict?

Question

Say you have 2 free functions:

void do_something(dog d);
void do_something(cat c);

No say you want to pass these functions to a templated function:

template <typename DoSomethingFunc>
void do_something_template(DoSomethingFunc func);

What would be the preferred way to call do_something_template in a manner that avoids overload resolution conflicts? Would it be casting?

Answer 1

You could cast or use a local function pointer variable.

void (*p)(dog) = do_something;
do_something_template(p);

---

do_something_template(static_cast<void(*)(cat)>(do_something));
