lbdb_dotlock - Lock mail spool files.


lbdb_dotlock [-t|-f|-u|-d] [-r retries] file


dotlock implements the traditional mail spool file locking method: To lock file, a file
named file.lock is created.


-t Just try. dotlock won't actually lock a file, but inform the invoking process if
it's at all possible to lock file.

-f Force the lock. If another process holds a lock on file longer than a certain
amount of time, dotlock will break that lock by removing the lockfile.

-u Unlock. dotlock will remove file.lock.

-d Delete. dotlock will lock file, remove it if it has length 0, and afterwards
remove file.lock.

-r retries
This command line option tells dotlock to try locking retries times before giving
up or (if invoked with the -f command line option) break a lock. The default value
is 5. dotlock waits one second between successive locking attempts.
