Explain ? Yes indeed...

A pointer points (Yes, this is his job !) to a certain piece of memory. If 
you don't initialise the part of memory where it points, you might get 
unpredictable values through the pointer or sometimes memory crashes.

When you declare a pointer like :

struct _s *next;

C++ knows that the next pointer points to a part of memory that contains a 
"struct _s" type of data. BUT a first, the pointer points to...nothing or 
random adress ! You first have to allocate some memory (malloc) to receive a 
struct _s data. Then, acessing to the "next" pointer gives you access to a 
struct _s for *real* this time.

But, if you think you're not a CPP hero, I think you might get some books 
about it and read it from cover to cover.

There are a huge amount of tutorials for newbies almost everywhere on the 
net. Just check out Google for this.

Kind regards
