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 alen,
       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 contents 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;
           };
