Brendan Coles 89265be167 Base: Add man pages for null/zero/full character devices

2021-03-04 09:19:15 +01:00

Name

full - always full device

/dev/full is a character device which is always full.

Reading from /dev/full returns '\0' bytes and exits with status 0.

Writing to /dev/full fails with ENOSPC error.

To create it manually:

mknod /dev/full c 1 7
chmod 666 /dev/full

$ head -c 8 /dev/full | hexdump
