Thread: Help with lists please

Hi! Im trying to learn about lists in C but I cannot get it , here is part of an example taken from a book:

Code:

 
struct tlist{
        long DNI;
        char Name[25];
        int  Age;
        struct tlist *pnext; //Pointer to next element.
     };
 
     void main(void)
     {
        struct tlist *list = NULL; //Empty.
        struct tlist *p; //Auxiliar pointer.

Well I understand what the first struct does, but the 2 lines in main function cannot understand what exactly does, why are both pointers? these pointers are the pointers that are inside of the struct? I need some help from you guys, maybe a book or a web where its well explained.

Try this C Linked List Data Structure Explained with an Example C Program cuz it works for me!

And next time please try googling for the such materials because what works for me may not work for you thats why google gives variety varieties.
