How do you create special files like named pipes and device files?

The system call method forms special files in the following sequence.

  • Kernel assigns new inode,
  • Sets the file type to show that the file is a pipe, directory or special file,
  • If it is a device file, it makes the other entries like main, minor device numbers.

For example:

If the device is a disk, main device number refers to the disk controller and minor device number is the disk.
