#include <ares.h>

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

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(3).

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;
};

ares_parse_srv_reply can return any of the following values:

15 ARES_SUCCESS The response was successfully parsed.

15 ARES_EBADRESP The response was malformatted.

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

15 ARES_ENOMEM Memory was exhausted.
