error C2436 member function or nested class in constructor initializer list

Question

I have a function pointer declared in my header, like this:

typedef void (intCB)(int );

and I have a class member declared like this:

private:
  intCB m_intCB;

In my constructor's initialization list I want to initialize it with 0:

MyClass::MyClass : m_intCB(0)
{
   #ifdef SOMETHING
   m_intCB = &someOtherFunc;
   #endif
}

Only if a specific define is in place, I want to set m_intCB to it, if not I want to keep it on 0. The problem with the above code is that I receive:

error C2436: 'm_intCB' : member function or nested class in constructor initializer list

How can I fix it?

Answer 1

That's not a function pointer, you are missing a *. Try:

typedef void (*intCB)(int);

Answer 2

Your typedef is wrong, it should be typedef void (*intCB)(int );
