INTERFACE LEVEL

     Architecture independent level 1 (DDI/DKI).

     majnum
           Major device number.

     minnum
           Minor device number.

DESCRIPTION

     makedevice() creates a device number from a major and  minor
     device  number.   makedevice() should be used to create dev-
     ice 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

     makedevice() can be called from user or interrupt context.
