! The \fBioctls\fR listed in this manual page apply directly to sockets,
! independent of any underlying protocol. The \fBsetsockopt()\fR call (see
! \fBgetsockopt\fR(3SOCKET)) is the primary method for operating on sockets,
! rather than on the underlying protocol or network interface. \fBioctl\fRs for a
! specific network interface or protocol are documented in the manual page for
! that interface or protocol.

! The argument is a pointer to an \fBint\fR. Set the process-group \fBID\fR that
! will subsequently receive \fBSIGIO\fR or \fBSIGURG\fR signals for the socket
! referred to by the descriptor passed to \fBioctl\fR to the value of that
! \fBint\fR. The argument must be either positive (in which case it must  be a

  in the data stream for an  out-of-band message.
