One possibility is to create a temporary file somewhere, but if the app
crashes or the process is terminated by the user you will not be able to
erase it.

There are other possibilities like opening a localconnection (names
should be unique I think) or a socket. Or you will have to write C code
to list the running processes and/or create a named pipe (on windows).
