Passing function pointer in a variable

We are continuing with the previous example, and now we want to pass a pointer to a function in our process_integers() method. Shall we add an overload for just function pointers, or is there a more elegant way?

Getting ready

This recipe is continuing the previous one. You must read the previous recipe first.

How to do it...

Nothing needs to be done as boost::function<> is also constructible from the function pointers:

void my_ints_function(int i); 
 
int main() { 
    process_integers(&my_ints_function); 
}
