20 The \fBkillpg()\fR function sends the signal \fIsig\fR to the process group
21 \fIpgrp\fR. See \fBsignal.h\fR(3HEAD) for a list of signals.
24 The real or effective user \fBID\fR of the sending process must match the real
25 or saved set-user \fBID\fR of the receiving process, unless the effective user
26 \fBID\fR of the sending process is the privileged user. A single exception is
27 the signal \fBSIGCONT\fR, which may always be sent to any descendant of the
32 Upon successful completion, \fB0\fR is returned. Otherwise, \fB\(mi1\fR is
33 returned and \fBerrno\fR is set to indicate the error.
37 The \fBkillpg()\fR function will fail and no signal will be sent if:
44 The \fIsig\fR argument is not a valid signal number.
53 The effective user \fBID\fR of the sending process is not privileged user, and
54 neither its real nor effective user \fBID\fR matches the real or saved set-user
55 \fBID\fR of one or more of the target processes.
64 No processes were found in the specified process group.
