## NAME
       full - always full device

## CONFIGURATION
       If  your system does not have _/dev/full_ created already, it can be created with the following
       commands:

           mknod -m 666 /dev/full c 1 7
           chown root:root /dev/full

## DESCRIPTION
       The file _/dev/full_ has major device number 1 and minor device number 7.

       Writes to the _/dev/full_ device fail with an **ENOSPC **error.  This can be used  to  test  how  a
       program handles disk-full errors.

       Reads from the _/dev/full_ device will return \0 characters.

       Seeks on _/dev/full_ will always succeed.

## FILES
       _/dev/full_
