Synopsis

#include <ares.h>

Description

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.

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;
};
