       NAME
             clone - open any major/minor device pair on a STREAMS driver

       DESCRIPTION
             clone is a STREAMS software driver that finds and opens an
             unused major/minor device on another STREAMS driver.  The
             major device number passed to clone during open corresponds to
             the clone driver and the minor device number corresponds to
             the target driver.  Each open results in a separate stream to
             a previously unused major/minor device.

             The clone driver consists solely of an open function.  This
             open function performs all of the necessary work so that
             subsequent system calls [including close(2)] require no
             further involvement of clone.

             clone will generate an ENXIO error, without opening the
             device, if the major/minor device number provided does not
             correspond to a valid major/minor device, or if the driver
             indicated is not a STREAMS driver.

       NOTICES
             Multiple opens of the same major/minor device cannot be done
             through the clone interface.  Executing stat(2) on the file
             system node for a cloned device yields a different result from
             executing fstat using a file descriptor obtained from opening
             the node.
