sockio(7)                                                  sockio(7)


       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 getsockopt(3N)) 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.

             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.
