Programs may add one or more signals to -the set, and then perform an `async_wait()` operation. The specified handler -will be called when one of the signals occurs. The same signal number may be -registered with multiple [link asio.reference.signal_set signal_set] objects, -however the signal number must be used only with Asio. - - void handler( - const asio::error_code& error, - int signal_number) - { - if (!error) - { - // A signal occurred. - } - } - - ... - - // Construct a signal set registered for process termination. - asio::signal_set signals(io_context, SIGINT, SIGTERM); - - // Start an asynchronous wait for one of the signals to occur. - signals.async_wait(handler); - -Signal handling also works on Windows, as the Microsoft Visual C++ runtime -library maps console events like Ctrl+C to the equivalent signal. - -[heading See Also] - -[link asio.reference.signal_set signal_set], -[link asio.examples.cpp03_examples.http_server HTTP server example (C++03)], -[link asio.examples.cpp11_examples.http_server HTTP server example (C++11)]. - -[endsect] |
