|
|
of the entry. In the first form, the second argument is
|
|
.B b
|
|
if the special file is block-type (disks, tape) or
|
|
.B c
|
|
if it is character-type (other devices). The last two arguments are
|
|
numbers specifying the
|
|
.I major
|
|
device type and the
|
|
.I minor
|
|
device (for example, unit, drive, or line number).

|
Only the super-user is permitted to invoke this form of the
|

The first form of

|

|
|
instead when making special files.
