NAME

     ares_parse_srv_reply - Parse a reply to a DNS query of  type
     SRV

SYNOPSIS

     #include <ares.h>

     int ares_parse_srv_reply(const unsigned char* abuf, int
     struct ares_srv_reply** srv_out);

DESCRIPTION

     The ares_parse_srv_reply function parses the response  to  a
     query   of   type   SRV   into   a  linked  list  of  struct
     ares_srv_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  srv_out.   It is the caller's responsibility to free
     the resulting srv_out structure when it is no longer  needed
     using the function ares_free_data

     The structure ares_srv_reply contains the following fields:

         struct ares_srv_reply {
             struct ares_srv_reply  *next;
             unsigned short weight;
             unsigned short priority;
             unsigned short port;
             char *host;
         };

RETURN VALUES

     ares_parse_srv_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.
