       Fetches  the  "authMechanismProperties"  options  set  on this mongoc_uri_t. The out-parameter properties
       should be an uninitialized, stack-allocated bson_t. It is statically initialized with  bson_init_static()
       to  point  to the internal data of uri, so its contents must not be modified and it becomes invalid after
       uri is destroyed.

          mongoc_uri_t *uri;
          bson_t props;

          uri = mongoc_uri_new (
             "mongodb://user%40DOMAIN.COM:password@localhost/?authMechanism=GSSAPI"
             "&authMechanismProperties=SERVICE_NAME:other,CANONICALIZE_HOST_NAME:true");

          if (mongoc_uri_get_mechanism_properties (uri, &props)) {
             char *json = bson_as_canonical_extended_json (&props, NULL);
             printf ("%s\n", json);
             bson_free (json);
          } else {
             printf ("No authMechanismProperties.\n");
          }

       This code produces the output:

          { "SERVICE_NAME" : "other", "CANONICALIZE_HOST_NAME" : "true" }

       • uri: A mongoc_uri_t.

       • properties: An uninitialized bson_t.

       If no "authMechanismProperties" have been set on uri, this functions returns false and properties remains
       uninitialized.
