You need to read and understand topics linked from this overview page: https://docs.microsoft.com/en-us/windows/desktop/ipc/named-pipes I'm unsure whether all the necessary steps are achievable using only asio (e.g., CreateNamedPipe and ConnectNamedPipe). -----Original Message----- From: Boost-users On Behalf Of parean via Boost-users Sent: Wednesday, March 20, 2019 07:01 To: boost-users@lists.boost.org Cc: parean Subject: [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 _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org https://lists.boost.org/mailman/listinfo.cgi/boost-users
