ares_parse_uri_reply - Parse a reply to a DNS query of type URI

#include <ares.h>
int ares_parse_uri_reply(const unsigned char* abuf, int alen,
struct ares_uri_reply** uri_out);

The ares_parse_uri_reply 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

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; };

ares_parse_uri_reply can return any of the following values:

The response was successfully parsed.
The response was malformatted.
The response did not contain an answer to the query.
Memory was exhausted.

ares_query(3) ares_free_data(3)
