MAKEDEVICE(9F) Kernel Functions for Drivers MAKEDEVICE(9F)

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.
