SYNOPSIS

#include <ares.h>

                         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(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_SUCCESS: The response was successfully parsed.
ARES_EBADRESP: The response was malformatted.
ARES_ENODATA: The response did not contain an answer to the query.
