kill(2) man page: ESRCH

[Ed Schouten]

Hi all,

Just a quick question. The kill(2) man page says:

     The kill() system call will fail and no signal will be sent if:

     [ESRCH]            The process id was given as 0 but the sending process
                        does not have a process group.

My question is: is this possible? I thought all processes have a process
group. POSIX also doesn't mention anything about this case specifically.
Shall I zap this?
