KILL(II) 8/5/73 KILL(II) NAME kill - send signal to a process SYNOPSIS (kill = 37.; not in assembler) (process number in r0) sys kill; 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 controlling typewriter, otherwise this call is restricted to the super-user. SEE ALSO signal(II), kill(I) DIAGNOSTICS The error bit (c-bit) is set if the process does not have the same controlling typewriter and the user is not super- user, or if the process does not exist. BUGS Equality between the controlling typewriters of the sending and receiving process is neither a necessary nor sufficient condition for allowing the sending of a signal. The correct condition is equality of user IDs.
