llist_t and llist_pop

[Yann E. MORIN]

Hello!

Would anybody care to explain why llist_t is defined that way:

typedef struct llist_s {
    char *data;
    struct llist_s *next;
} llist_t;

and why llist_pop returns void* :

extern void *llist_pop(llist_t **elm);

when it returns the data field (a char*) of a llist_t structure?

Regards,
Yann E. MORIN.
