How can I easily call sd_notify (specifically watchdog=1) from a
command line app I have created. I am wanting systemd to restart the
app if the watchdog stops  responding for some reason. Thanks in
advance :-)

You can use TProcess to run it. I'm not aware of na FPC interface to
the library code... but there's a lot I don't know.
