I'm making some assumptions here. Feel free to ask if they're wrong, or you need more information.

/* A list element containing a pointer to the next one */
struct elm
{   ...
    struct elm *next;

/* a utility pointer */
struct elm *lp;

/* pointer to head of list */
struct elm *head;

int i;

for(i=0,lp=head; i<7; ++i)lp=lp->next;

That's the basic idea.
