+ * Add a variable array of basic data elements to a data descriptor.
+ * @param edd The data descriptor to add the type to.
+ * @param struct_type The type of the struct.
+ * @param name The string name to use to encode/decode this member
+ *        (must be a constant global and never change).
+ * @param member The struct member itself to be encoded.
+ * @param type The type of the member to encode.
+ *
+ * This macro lets you easily add a variable size array of basic data
+ * types. All the parameters are the same as for
+ * EET_DATA_DESCRIPTOR_ADD_BASIC(). This assumes you have
+ * a struct member (of type EET_T_INT) called member_count (note the
+ * _count appended to the member) that holds the number of items in
+ * the array. This array will be allocated separately to the struct it
+ * is in.
