DESCRIPTION

       The bson_value_t structure is a boxed type for encapsulating a runtime determined type.

EXAMPLE

          const bson_value_t *value;

          value = bson_iter_value (&iter);

          if (value->value_type == BSON_TYPE_INT32) {
             printf ("%d\n", value->value.v_int32);
          }
