+ * Function: H5Tinsert_array
+ *
+ * Purpose: Adds another member to the compound data type PARENT_ID. The
+ * new member has a NAME which must be unique within the
+ * compound data type. The OFFSET argument defines the start of
+ * the member in an instance of the compound data type and
+ * MEMBER_ID is the type of the new member. The member is an
+ * array with NDIMS dimensionality and the size of the array is
+ * DIMS. The total member size should be relatively small.

+ * Return: Success: SUCCEED

+ * Failure: FAIL
