       ares_parse_soa_reply - Parse a reply to a DNS query of type SOA

       #include <ares.h>

       int ares_parse_soa_reply(const unsigned char* abuf, int alen,
		      struct ares_soa_reply** soa_out);

       The  ares_parse_soa_reply  function  parses  the  response  to  a query of type SOA into a
       struct ares_soa_reply.  The parameters abuf and alen give the contents  of  the	response.
       The  result  is	stored	in  allocated memory and a pointer to it stored into the variable
       pointed to by soa_out.  It is the caller's responsibility to free  the  resulting  soa_out
       structure when it is no longer needed using the function ares_free_data

       The structure ares_soa_reply contains the following fields:

	   struct ares_soa_reply {
		char *nsname;
		char *hostmaster;
		unsigned int serial;
		unsigned int refresh;
		unsigned int retry;
		unsigned int expire;
		unsigned int minttl;

       ares_parse_soa_reply can return any of the following values:

       ARES_SUCCESS   The response was successfully parsed.

       ARES_EBADRESP  The response was malformatted.

       ARES_ENODATA   The response did not contain an answer to the query.

       ARES_ENOMEM    Memory was exhausted.

       This function was first introduced in c-ares version 1.9.0.
