Prototype
int lfds600_slist_get_user_data_from_element( struct lfds600_slist_element *se, void **user_data );
Parameters
struct lfds600_slist_element *se
- A pointer to an slist element as allocated by lfds600_slist_new_head or lfds600_slist_new_next.
void **user_data
- A pointer to a pointer into which the user data will be placed.
Return Value
Returns 1 on success, 0 on failure. The only cause of failure is if you try to get the user data from an element which has been logically deleted.
Notes
This function gets the user data void pointer in the slist element.
