cmake .. -DBUILD_EXAMPLE=On # to also build example
makeThis plugin is a wrapper on "sd_notify" see man page here
When Operating Status is set at "InService" we notify systemd with a "READY=1" and when the Operating Status is set to "Stopping" or "Shutting Down" we notify systemd with "STOPPING=1". This allow systemd to syncronize process in a better way.
As an extra status for the service, for all Operating Status and Health States, we notify systemd with the "STATUS=Operating Status <X>, Health State <Y> "
By default the plugin is install here "$(PREFIX_LIBEXECDIR)/service_status_plugins/libfty-service-status-systemd.so"
The error codes return by the functions of the plugin are the one of "sd_notify" see man page here
