[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? -- Sent from: http://boost.2283326.n4.nabble.com/Boost-Users-f2553780.html
