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 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, interrupt, or kernel
context.
