NAME

       mknod.h - header file of macros for handling device numbers

SYNOPSIS

DESCRIPTION

       The header file defines macros to create and interpret device identification numbers for use with the system call (see mknod(2)).

       The  use  of these macros is architecture-dependent.  See the System Administration Manual for your system for information on how to select
       major and minor device numbers.

       contains the macro

       which packs the major and minor components into a device identification number suitable for the dev argument of and the two macros:

       which extract the major and minor number components, respectively, from a device identification number, dev.

       The macro is a specification (see printf(3S)) that prints the minor number in the format best suited to the particular  implementation;	it
       is used by the long format of the command (see ls(1)) to show the minor numbers for device files.

       The  base of the number is indicated in the same way as in the C programming language: no leading zero for decimal, leading zero for octal,
       and leading for hexadecimal.

NAME

       mknod - Creates a special file

SYNOPSIS

       /usr/sbin/mknod special_file [ b major_device# minor_device# |  c major_device# minor_device#]

       /usr/sbin/mknod filename p

DESCRIPTION

       The  mknod  command makes a directory entry.  The first argument is the name of the special device file.  Select a name that is descriptive
       of the device.

       The mknod command has two forms.  In the first form, the second argument is the b or c flag.  The last two arguments are numbers specifying
       the major_device, which helps the operating system find the device driver code, and the minor_device, the unit drive, or line number, which
       may be either decimal or octal.

       The assignment of major device numbers is specific to each system.  You can determine the device numbers by  examining  the  conf.c  system
       source file.  If you change the contents of the conf.c file to add a device driver, you must rebuild the kernel.

       In the second form of mknod, you use the p flag to create named pipes (FIFOs).

       Only the superuser can create a character or device special file.

FLAGS

       Indicates  that	the  special  file  corresponds to a block-oriented device (disk or tape) Indicates that the special file corresponds to a
       character-oriented device Creates named pipes (FIFOs)

EXAMPLES

       To create the special file for a new drive, /dev/disk/dsk20, with a major device number of 1 and a minor device number of 2,  enter:  mknod
       /dev/disk/dsk20	b   1	2 This command creates the special file, /dev/disk/dsk20, which is a block special file with major device number 1
       and minor device number 2.  To create a pipe named fifo, enter: mknod fifo p This command creates the pipe fifo, which is  not  necessarily
       in the current directory.
