KILL(2) 							System Calls Manual							   KILL(2)

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. ASSEMBLER
(kill = 37.) (process number in r0) sys kill; sig KILL(2)
