kill

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
