# interface must both use the same key. The "ftok" function facilitates creating
# such a key based on a shared piece of information that is not likely to
# conflict with keys chosen by any other process in the system.

# parameter. This file or dir must already exist and the permissions on it don't
# seem to matter. The inode of a particular file or dir is fairly unique but
# doesn't change often so it makes a decent choice for a key. We use the parent
# directory of the TWCManager script.
#
# The second parameter to ftok is a single byte that adds some additional
# uniqueness and lets you create multiple queues linked to the file or dir in
# the first param. We use 'T' for Tesla.
