Just so no one gets confused, C pointers *are* addresses. You pass an address wherein something is contained ... it could be a single address containing an integer number, or it could be the beginning byte of one of these complex structures. C, unlike Foxpro, knows how big the thing is that begins at that address because you cannot declare a variable in C without telling the compiler the type of the variable.

Sorry for being a stickler for details, but I thought there was a great margin there where somebody could get confused by the language that said "C pointers are like addresses."
