     #include 
     #include 



     dev_t makedevice(major_t majnum, minor_t minnum);


INTERFACE LEVEL
     Architecture independent level 1 (DDI/DKI).

PARAMETERS
     majnum    Major device number.


     minnum    Minor device number.


DESCRIPTION
     The makedevice() function creates a  device  number  from  a
     major  and  minor device number. makedevice() should be used
     to create device numbers so the driver will port  easily  to
     releases that treat device numbers differently.

RETURN VALUES
     The device number, containing both the major number and  the
     minor  number,  is  returned.  No validation of the major or
     minor numbers is performed.

CONTEXT
     The makedevice() function can be called  from  user,  inter-
     rupt, or kernel context.
