SYNOPSIS

          mongoc_server_description_t **
          mongoc_client_get_server_descriptions (const mongoc_client_t *client,
                                                 size_t *n) BSON_GNUC_WARN_UNUSED_RESULT;

       Fetches an array of mongoc_server_description_t structs for all known servers in the topology. Returns no
       servers  until  the  client connects. Returns a single server if the client is directly connected, or all
       members of a replica set if the client's MongoDB URI includes a "replicaSet" option, or all known  mongos
       servers if the MongoDB URI includes a list of them.

          void
          show_servers (const mongoc_client_t *client)
          {
             bson_t *b = BCON_NEW ("ping", BCON_INT32 (1));
             bson_error_t error;
             bool r;
             mongoc_server_description_t **sds;
             size_t i, n;

             /* ensure client has connected */
             r = mongoc_client_command_simple (client, "db", b, NULL, NULL, &error);
             if (!r) {
                MONGOC_ERROR ("could not connect: %s\n", error.message);
                return;
             }

             sds = mongoc_client_get_server_descriptions (client, &n);

             for (i = 0; i < n; ++i) {
                printf ("%s\n", mongoc_server_description_host (sds[i])->host_and_port);
             }

             mongoc_server_descriptions_destroy_all (sds, n);
             bson_destroy (&b);
          }

PARAMETERS

       • client: A mongoc_client_t.

       • n: Receives the length of the descriptions array.

RETURNS

       A newly allocated array that must be freed with mongoc_server_descriptions_destroy_all().
