It is advisable to use pointers when you use structures, because it is 
faster and more convenient. Suppose you have this structure:
struct foo{
   char *Text1;
   char *Text2;
   char *Text3;
};

If you have a function that has this structure as its argument, then it 
is better to pass only a pointer to it (&foo_struct), beacuse it already 
has pointers in it to character arrays, so you have the same result if 
you pass pointer or pass the whole struct. But when passing the whole 
struct, it will be copied, but the Texts won't, just the pointers to it. 
So it is better to pass only pointers to structs, always. It will make 
your code cleaner, and you can always assure yourself, that you always 
declared functions to use pointers.
