    I think alot of my problem is not understanding what a function is 
asking for when it's asking for a pointer. If it's asking for a pointer is 
it wanting what the pointer is pointing too. memset for example.

void *memset (void *s, int c, size_t n);

that first parameter. Is it want a pointer to something or to be passed what 
the pointer is pointing to. For example.

int *p;

memset(p,0,sizeof(int));
or memset(&p,0,sizeof(int));

Is such a thing as a function that wants this?

function (int &a, short &b);

If something is defined like that would you just pass the pointer?
