The Boost implementation is tracking those changes. Why don't you connect unused hot and neutral wires to "complete the circuit"? C++11 The library is documented to use several C++11 features, including noexcept and explicit conversion operators. c++ boost error-handling boost-asio share|improve this question edited Sep 9 '12 at 21:20 Sam Miller 18.1k34373 asked May 25 '12 at 13:14 user1307957 49516 What type is error?
