SYNOPSIS

#include <ares.h>

int ares_parse_uri_reply(const unsigned char* abuf, int alen,
                         struct ares_uri_reply** uri_out);

DESCRIPTION

The ares_parse_uri_reply(3) function parses the response to a query of type URI into a linked list of struct ares_uri_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 uri_out. It is the caller's responsibility to free the resulting uri_out structure when it is no longer needed using the function ares_free_data(3).

The structure ares_uri_reply contains the following fields:

struct ares_uri_reply {
    struct ares_uri_reply       *next;
    unsigned short              weight;
    unsigned short              priority;
    char                        *uri;
    int                         ttl;
};

RETURN VALUES

ARES_SUCCESS: The response was successfully parsed.
ARES_EBADRESP: The response was malformatted.
