However I have a daemon that writes its PID to an external file when it starts up and I have a script that looks for this file, extracts the PID in order to provide a commandline interface that allows the process to be killed. However, when I call getpid to write the PID to the text file it always seems to write a value that is 1 less than the PID shown when I use ps to view the process in question. Also if I call kill on the value returned by getpid it tells me that the process doesn't exist. It would seem that ps is right an getpid is wrong. I can obviously just add one to the value returned by getpid, but is this safe/future-proof? Is this a known issue? What should I do? Kirby You have a bug in your daemon.
