KILL(II) 12/15/74 KILL(II) 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.
