When registering a signal, it is now possible to pass flags that specify the behaviour associated with the signal. These flags are specified as an enum type in a new class, signal_set_base, and are passed to the underlying sigaction() call. For example: asio::signal_set sigs(my_io_context); sigs.add(SIGINT, asio::signal_set::flags::restart); Specifying flags other than flags::dont_care will fail unless sigaction() is supported by the target operating system. Since signal registration is global, conflicting flags (multiple registrations that pass differing flags other than flags::dont_care) will also result in an error.
