    Create an array of pointers and let each pointer point to the start of a linked list.

    I don't know, but maybe something like this?

    Code:
    /* For improving code readability */
    typedef struct node *list_ptr;
    typedef struct node *node_ptr;
    
    /* Also for improving code readability */
    typedef enum
    {
        FIRST_LIST,
        SECOND_LIST,
        NR_OF_LISTS
    } list_index;
    
    /* The basic element of a list */
    struct node
    {
        int some_useful_data;
        node_ptr next_node;
    };
    
    /* Some lists */
    list_ptr list1;
    list_ptr list2;
    
    /* An array of lists */
    list_ptr array_of_lists [NR_OF_LISTS];
    
    /* Filling the array */
    array_of_lists [FIRST_LIST] = list1;
    array_of_lists [SECOND_LIST] = list2;
