Hi! I've just had a situation, where I want to know the pid of the already running daemon, but i don't want to create the pidfile in case if there is no daemon running. Such a situation can occur if the daemon has some kind of controlling program. This program should be able to know the pid of the daemon (to send a signal, or for some logging purposes). With current pidfile API I don't see an appropriate way to do it. Pidfile_open() call can provide us with the PID. But if there is no daemon, this call will create the pidfile - and we'll have to use pidfile_remove() to do the cleanup. This behaviour doesn't seem to be appropriate. Is it possible to introduce some function to return the pid of the already running daemon or (-1), for example, if no daemon exists. Possible syntax can be: int pidfile_check(pid_t *pidptr); What do you think about that? With best regards, MichaelReceived on Tue Dec 20 2005 - 08:48:47 UTC
