/**
 * The GSList structure and its associated functions provide a
 * standard singly-linked list data structure.
 *
 * Each element in the list contains a piece of data, together with a
 * pointer which links to the next element in the list. Using this
 * pointer it is possible to move through the list in one direction
 * only (unlike the Doubly-Linked Lists which
 * allow movement in both directions).
 *
 * The data contained in each element can be either integer values, by
 * using one of the Type
 * Conversion Macros, or simply pointers to any type of data.
 *
 * List elements are allocated from the slice allocator, which is more
 * efficient than allocating elements individually.
 *
 * Note that most of the GSList functions expect to be passed a
 * pointer to the first element in the list. The functions which insert
 * elements return the new start of the list, which may have changed.
 *
 * There is no function to create a GSList. NULL is considered to be
 * the empty list so you simply set a GSList* to NULL.
 *
 * To add elements, use g_slist_append(), g_slist_prepend(),
 * g_slist_insert() and g_slist_insert_sorted().
 *
 * To remove elements, use g_slist_remove().
 *
 * To find elements in the list use g_slist_last(), g_slist_next(),
 * g_slist_nth(), g_slist_nth_data(), g_slist_find() and
 * g_slist_find_custom().
 *
 * To find the index of an element use g_slist_position() and
 * g_slist_index().
 *
 * To call a function for each element in the list use
 * g_slist_foreach().
 *
 * To free the entire list, use g_slist_free().
