Sending a signal to pid of zero sends to all processes whose process - group ID is equal to the process group ID as the sender. - - 2. Sending a signal to pid of zero does not send to processes in another process group. - - - OUTPUT SPECIFICATIONS - - PASS : - kiltcs02 1 PASS The signal was sent to all processes in the process group. - kiltcs02 2 PASS The signal was not sent to selective processes that were not in the process group. - - FAIL : - kiltcs02 1 FAIL The signal was not sent to all processes in the process group. - kiltcs02 2 FAIL The signal was sent to a process that was not in the process group. - - BROK : - kiltcs02 # BROK System call XXX failed.
