killpg(3BSD) (BSD System Compatibility) killpg(3BSD)
NAME
killpg - (BSD) send signal to a process group
SYNOPSIS
/usr/ucb/cc [flag . . . ] file . . .
int killpg(int pgrp, int sig);
DESCRIPTION
killpg sends the signal sig to the process group pgrp. See
sigvec(3BSD) for a list of signals.
The real or effective user ID of the sending process must
match the real or saved set-user ID of the receiving process,
unless the effective user ID of the sending process is the
privileged user. A single exception is the signal SIGCONT,
which may always be sent to any descendant of the current
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.
ERRORS
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 processes were found in the specified
process group.
EPERM The effective user ID of the sending process is
not privileged user, and neither its real nor
effective user ID matches the real or saved
set-user ID of one or more of the target
processes.
