makedev(3c)

Standard C Library Functions                                       makedev(3C)



NAME
       makedev, major, minor - manage a device number

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

       dev_t makedev(major_t maj, minor_t min);


       major_t major(dev_t device);


       minor_t minor(dev_t device);


       minor_t maxminor();

DESCRIPTION
       The makedev() function returns a formatted device number on success and
       NODEV on failure. The maj argument is the major number. The  min  argu‐
       ment  is the minor number. The makedev() function can be used to create
       a device number for input to mknod(2).


       The major() function returns the major number component from device.


       The minor() function returns the minor number component from device.


       The maxminor() function returns the maximum supported minor number.

RETURN VALUES
       Upon successful completion, makedev() returns a formatted  device  num‐
       ber.  Otherwise,  NODEV  is  returned  and errno is set to indicate the
       error.

ERRORS
       The makedev() function will fail if:

       EINVAL    One or both of the arguments maj and min is too large, or the
                 device number created from maj and min is NODEV.



       The major() function will fail if:

       EINVAL    The  device  argument is NODEV, or the major number component
                 of device is too large.



       The minor() function will fail if:

       EINVAL    The device argument is NODEV.
