	    When  used	to  free  the  data  returned by ares_parse_srv_reply(3) this will free the whole linked list of ares_srv_reply structures
	    returned by ares_parse_srv_reply(3), along with any additional storage associated with those structures.

       ares_parse_mx_reply(3)
	    When used to free the data returned by ares_parse_mx_reply(3) this will  free  the	whole  linked  list  of  ares_mx_reply	structures
	    returned by ares_parse_mx_reply(3), along with any additional storage associated with those structures.

       ares_parse_txt_reply(3)
	    When  used	to  free  the  data  returned by ares_parse_txt_reply(3) this will free the whole linked list of ares_txt_reply structures
	    returned by ares_parse_txt_reply(3), along with any additional storage associated with those structures.

       ares_parse_soa_reply(3)
	    When used to free the data returned by ares_parse_soa_reply(3) this will free the ares_soa_reply structure, along with any	additional
	    storage associated with those structure.
