[Boost-users] Using async_pipe as named pipe in windows

I have this code:  

boost::asio::io_service ios;
  std::vector<char> buf(20);
  bp::async_pipe ap(ios, "\\\\.\\pipe\\SamplePipe");
  boost::asio::async_read(ap, boost::asio::buffer(buf),
    [](const boost::system::error_code &ec, std::size_t size) {});
  ios.run();

Now, I execute "echo 42 > \\.\pipe\SamplePipe" in the cmd and expect an
asynchronous read to the buffer to occur. But instead I get the following
error: "All pipe instances are busy." I'm sure I'm doing something wrong.
Can you please tell me what should I add to my code for it to work?
