The convention is:

# install the service
mysvc.exe -i

# uninstall the service
mysvc.exe -u

When your service is "installed", simply invoking it should cause it to
register itself with the service control manager, which can then send it
commands. This will make it work when the user does:

net start postmaster
net stop postmaster

This uses the same mechanism that gets used when you go to the Services
control panel and ask a service to stop.

When the user says "net stop postmaster", an entry point in
postmaster will be called by the Service Control Manager. Then
postmaster will have to send the signals to the other processes
asking them to stop and presumably wait for them to stop before
terminating itself.
