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

File /dev/full has major device number 1 and minor device number 7.

Writes to the /dev/full device will 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.
