>From the rhapsody kill(2) man page:

     The kill() function sends the signal given by sig to pid, a process or a
     group of processes.  Sig may be one of the signals specified in sigacĀ­
     tion(2) or it may be 0, in which case error checking is performed but no
     signal is actually sent.  This can be used to check the validity of pid.
