I was just wondering how you would get a pointer to a function in C++. Let me clarify:

  

int main()
{
return 0;
}

int AFunction() //Want The Pointer To This Function

{
return 0;
}

I checked my MSDN cd. Can''t find it. Anyone know how?

int (*func)();

func = AFunction;

All I get is 0x000000.

I can''t get it to put the memory address in the pointer function.

thats weird, what TV posted is accurate. make sure the arg signature and return tryp matches, ie:

  float MyFunc(int x, bool b){...}typedef float(*FuncPtr)(int,bool);void main(){    FuncPtr func = MyFunc;    func(0, true);}

Make sure you don''t have:

func = AFunction(); // will execute AFunction

but

func = AFunction; // will take the address of AFunction
