#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;

The response was successfully parsed.


The response was malformatted.


The response did not contain an answer to the query.
