       F_GETOWN Get  the  process  ID  (or  process group) of the
                owner of a socket.

                Process groups are returned as negative values.

       F_SETOWN Set the process or  process  group  that  owns  a
                socket.

                For  these  commands,  ownership  means receiving
                SIGIO or SIGURG signals.

                Process groups are specified using negative  val-
                ues.

This reads the same as the BSD one :

     F_GETOWN   Get the process ID or process group currently receiving SIGIO
                and SIGURG signals; process groups are returned as negative
                values (arg is ignored).

     F_SETOWN   Set the process or process group to receive SIGIO and SIGURG
                signals; process groups are specified by supplying arg as neg-
                ative, otherwise arg is interpreted as a process ID.
