    // type of the function which can be registered as signal handler: notice
    // that it isn't really a signal handler, i.e. it's not subject to the
    // usual signal handlers constraints, because it is called later from
    // CheckSignal() and not when the signal really occurs
    typedef void (*SignalHandler)(int);

    // Set signal handler for the given signal, SIG_DFL or SIG_IGN can be used
    // instead of a function pointer
    //
    // Return true if handler was installed, false on error
    bool SetSignalHandler(int signal, SignalHandler handler);

    // Check if any Unix signals arrived since the last call and execute
    // handlers for them
    void CheckSignal();

private:
    // signal handler set up by SetSignalHandler() for all signals we handle,
    // it just adds the signal to m_signalsCaught -- the real processing is
    // done later, when CheckSignal() is called
    static void HandleSignal(int signal);
