buildDaemon.run

Starts daemon that is described by DaemonInfo. Daemon is implemented as windows service and auto-installed in SC manager. If you want to uninstall the service, you can use uninstall function or system call:

C:\Windows\System32\sc.exe delete <daemonName>

If the service is already installed and is stopped, the function tries to start daemon. Otherwise it fails and returns EXIT_FAILURE code.

logger is a initialized logger for the daemon, you should use absolute names for Windows for logger files.

pidFilePath, lockFilePath, userId and groupId are ignored for Windows platform.

)

Examples

// First you need to describe your daemon via template
alias daemon = Daemon!(
    "DaemonizeExample1", // unique name

    // Setting associative map signal -> callbacks
    KeyValueList!(
        Composition!(Signal.Terminate, Signal.Quit, Signal.Shutdown, Signal.Stop), (logger, signal)
        {
            logger.logInfo("Exiting...");
            return false; // returning false will terminate daemon
        },
        Signal.HangUp, (logger)
        {
            logger.logInfo("Hello World!");
            return true; // continue execution
        }
    ),

    // Main function where your code is
    (logger, shouldExit) {
        // will stop the daemon in 5 minutes
        auto time = Clock.currSystemTick + cast(TickDuration)5.dur!"minutes";
        bool timeout = false;
        while(!shouldExit() && time > Clock.currSystemTick) {  }

        logger.logInfo("Exiting main function!");

        return 0;
    }
);
