NAME
       makedevice - make device number from major and minor numbers

SYNOPSIS
       #include <sys/types.h>
       #include <sys/mkdev.h>
       #include <sys/ddi.h>

       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 num-
       bers 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  per-
       formed.

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