Another way would be to use dbus, or any other kind of registry that
will safely relinquish the unique name upon exit of your process.

A portable way is to use file locking (although the APIs are different for
Windoze/POSIX). An application starts, creates a file with the same pathname and
then tries to lock it. If locking succeeds this is the first instance of
application. When the application terminates for any reason the operating system
releases the file lock.

That's nice, but has little to do with C++ per se.
