typo mapNode[6]* exits; instead of mapNode*[6] exits; but whats it mean ?

I'm not sure I understand what mapNode[6]* means! (the second 
version is what I wanted an array of 6 pointers)

oddly when assigning a null to one element of the array it cause 
an error as it was trying to do an array copy... so what's going 
on and what does that definition actually mean ?
