full - always full device
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
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.
