ARES_PARSE_NAPTR_REPLY(3C LIBRARY FUNCTIONARES_PARSE_NAPTR_REPLY(3)

NAME

     ares_parse_naptr_reply - Parse a reply to  a  DNS  query  of
     type NAPTR

SYNOPSIS

     #include <ares.h>

     int ares_parse_naptr_reply(const unsigned char* abuf, int
     struct ares_naptr_reply** naptr_out);

DESCRIPTION

     The ares_parse_naptr_reply function parses the response to a
     query   of   type   NAPTR  into  a  linked  list  of  struct
     ares_naptr_reply The parameters abuf and alen give the  con-
     tents  of  the  response.  The result is stored in allocated
     memory and a pointer to it stored into the variable  pointed
     to  by naptr_out.  It is the caller's responsibility to free
     the resulting naptr_out  structure  when  it  is  no  longer
     needed using the function ares_free_data

     The  structure  ares_naptr_reply  contains   the   following
     fields:

         struct ares_naptr_reply {
             struct ares_naptr_reply *next;
             unsigned char *flags;
             unsigned char *service;
             unsigned char *regexp;
             char *replacement;
             unsigned short order;
             unsigned short preference;
         };

RETURN VALUES

     ares_parse_naptr_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.
