KILLPG(2)               COMMAND REFERENCE               KILLPG(2)



NAME
     killpg - send signal to a process group

SYNOPSIS
     killpg(pgrp, sig)
     int pgrp, sig;

DESCRIPTION
     Killpg sends the signal sig to the process group pgrp.  See
     sigvec(2) for a list of signals.

     The sending process and members of pgrp must have the same
     effective user ID, otherwise this call is restricted to the
     super-user.  As a single special case the continue signal
     SIGCONT may be sent to any process which is a descendant of
     the current process.

DIAGNOSTICS
     Killpg will fail and no signal will be sent if any of the
     following occur:

     [EINVAL]
         Sig is not a valid signal number.

     [ESRCH]
         No process can be found corresponding to that specified
         by pid.

     [EPERM]
         The sending process is not the super-user and one or
         more of the target processes has an effective user ID
         different from that of the sending process.

RETURN VALUE
     Upon successful completion, a value of 0 is returned.
     Otherwise, a value of -1 is returned and the global variable
     errno is set to indicate the error.
