Apply a FL_FLOCK
style lock to an open file descriptor.
The cmd can be one of
LOCK_SH
-- a shared lock.
LOCK_EX
-- an exclusive lock.
LOCK_UN
-- remove an existing lock.
LOCK_MAND
-- a `mandatory' flock. This exists to emulate Windows Share Modes.
LOCK_MAND
can be combined with LOCK_READ
or LOCK_WRITE
to allow other
processes read and write access respectively.
