NAME
       sockio - ioctls that operate directly on sockets

SYNOPSIS
       #include <sys/sockio.h>

DESCRIPTION
       The  ioctls  listed  in this manual page apply directly to sockets, independent of any underlying protocol. The setsockopt() call (see get-
       sockopt(3SOCKET)) is the primary method for operating on sockets, rather than on the underlying protocol or network interface. ioctls for a
       specific network interface or protocol are documented in the manual page for that interface or protocol.

       SIOCSPGRP      The argument is a pointer to an int. Set the process-group ID that will subsequently receive SIGIO or SIGURG signals for the
		      socket referred to by the descriptor passed to ioctl to the value of that int. The argument  must  be  either  positive  (in
		      which case it must  be a process ID) or negative (in which case it must be a process group).

       SIOCGPGRP      The  argument  is  a  pointer to an int. Set the value of that int to the process-group ID that is receiving SIGIO or SIGURG
		      signals for the socket referred to by the descriptor passed to ioctl.

       SIOCCATMARK    The argument is a pointer to an int. Set the value of that int to 1 if the read pointer for the socket referred  to  by  the
		      descriptor passed to ioctl points to a mark in the data stream for an out-of-band message. Set the value of that int to 0 if
		      the read pointer for the socket referred to by the descriptor passed to ioctl  does not point to a mark in the  data  stream
		      for an  out-of-band message.
