Null Pointers?? I'm kinda sketchy on the concept and use of them. If anyone knows a link to an existing faq or something to that extent, I'd appreciate it!! Thanks

Null pointers .... hmm ... not really that much to say about that.
The address 0 is per definition not a valid address.
Thus if you have a function that is supposed to return an address it is the typical way the function tells the caller that something went wrong (like malloc does).
It's a 'disaster' if the caller doesn't check the pointer before use.
It's not very informative as to what the problem is, but the meaning is clear.
