/**
+ * @def EINA_VALUE_ARRAY_FOREACH
+ * @brief Definition for the macro to iterate over an array contained in an
Eina_Value.
+ *
+ * @param array The list to iterate over.
+ * @param length Contain the length of the array
+ * @param it Contain the current position walked over
+ * @param value Contain the value at the current position.
+ *
+ * This macro iterates over @p array from the first element to
+ * the last. @p value is the data related to the current element.
+ *
+ * It can be used like in the following example:
+ *
+ * @code
+ * Eina_Value array;
+ * Eina_Error err;
+ * unsigned int i, len;
+ * Eina_Value v = EINA_VALUE_EMPTY;
+ *
+ * // array is already filled,
+ * // its elements are unknown,
+ * // EINA_VALUE_ARRAY_FOREACH will be used to check if there is no error
+ *
+ *
+ * EINA_VALUE_ARRAY_FOREACH(&array, len, i, &v)
+ * {
+ * if (v.type == EINA_VALUE_TYPE_ERROR)
+ * {
+ * eina_value_get(&v, &err);
+ * fprintf(stderr, "Something has gone wrong: %s at index: %i\n",
eina_error_msg_get(err), i);
+ * abort();
+ * }
+ * }
+ * @endcode
+ *
+ * @warning @p array and v must be a pointer to an Eina_Value
