* @def EINA_ARRAY_ITER_NEXT
* @brief Macro to iterate over an array easily.
*
* @param array The array to iterate over.
* @param index The integer number that is increased while itareting.
* @param item The data
* @param iterator The iterator
*
* This macro allows the iteration over @p array in an easy way. It
* iterates from the first element to the last one. @p index is an
* integer that increases from 0 to the number of elements. @p item is
* the data of each element of @p array, so it is a pointer to a type
* chosen by the user. @p iterator is of type #Eina_Array_Iterator.
*
* This macro can be used for freeing the data of an array, like in
* the following example:
*
* @code
* Eina_Array *array;
* char *item;
* Eina_Array_Iterator iterator;
* unsigned int i;
*
* // array is already filled,
* // its elements are just duplicated strings,
* // EINA_ARRAY_ITER_NEXT will be used to free those strings
*
* EINA_ARRAY_ITER_NEXT(array, i, item, iterator)
* free(item);
* @endcode
