NAME

kill  −  send signal to a process

SYNOPSIS

(kill = 37.; not in assembler)
(process number in r0)
sys kill; sig kill(pid, sig);

DESCRIPTION

Kill sends the signal sig to the process specified by the process number in r0.  See signal (II) 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 which have the same controlling typewriter and user ID. In no case is it possible for a process to kill itself.

SEE ALSO

signal (II), kill (I)

DIAGNOSTICS

The error bit (c-bit) is set 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.  From C, −1 is returned.
