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:

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.
