ARES_PARSE_SOA_REPLY(3)C LIBRARY FUNCTIONSARES_PARSE_SOA_REPLY(3)

NAME

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

SYNOPSIS

     #include <ares.h>

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

DESCRIPTION

     The ares_parse_soa_reply function parses the response  to  a
     query of type SOA into a struct ares_soa_reply.  The parame-
     ters 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 struc-
     ture  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;
         };

RETURN VALUES

     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.
