pointer to a . function???????

Do be clear, you mean a member function pointer?

I am not sure that functions take up memory in the same way. What would you assign the value of the pointer to? What information does a function retain? I am pretty sure you can't, but I am still curious. Any experts on this?

Sure you can, at least in C...

Yes, you can create function pointers, but they're generally considered bad practice. As someone mentioned above, function-pointer.org is a good resource.

If you're using C++ you'll probably want to look into functors (function objects) as an alternative to function pointers, though it really depends what you're trying to do.

Sorry, I probably could have saved you both a little time by mentioning that the Function Pointer Tutorial, previously found at http://function-pointer.org/ has been moved to the address I mentioned above.

Agreeing with Ra, boost::function and boost::bind are the best things to happen to function pointers since sliced bread. That's right - sliced bread happened to function pointers. Link to boost in my signature.
