NAME
kill - send signal to a process
SYNOPSIS
kill(pid, sig);
DESCRIPTION
Kill
sends the signal
sig
to the process specified by the
process number in r0.
See
signal(2)
for a list of signals.
The sending and receiving processes must
have the same effective user ID, otherwise
this call is restricted to the super-user.
If the process number is 0,
the signal is sent to all other processes in the
sender's process group;
see
tty(4).
If the process number is -1, and the user is the super-user,
the signal is broadcast universally
except to processes 0 and 1, the scheduler
and initialization processes,
see
init(8).
Processes may send signals to themselves.
SEE ALSO
signal(2), kill(1)
DIAGNOSTICS
Zero is returned if the process is killed;
-1 is returned if the process does not
have the same effective user ID and the
user is not super-user, or if the process
does not exist.
