/**
 * @brief Returns a new accessor associated to a list.
 *
 * @param list The list.
 * @return A new accessor.
 *
 * This function returns a newly allocated accessor associated to
 * @p list. If @p list is @c NULL or the count member of @p list is
 * less or equal than 0, this function returns NULL. If the memory can
 * not be allocated, NULL is returned and #EINA_ERROR_OUT_OF_MEMORY is
 * set. Otherwise, a valid accessor is returned.
