ares_parse_srv_reply (3)

#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

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:

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.

This function was first introduced in c-ares version 1.7.0.
