> So long as we have a "lock" concept...
what you currently have is the concept known
to everyone and his dog as SCOPED LOCKING.
which is simply a convenient way to deal with
(acq/rel) LOCKS (mutexes, semaphores,
read/write locks, spinlocks,...).
e.g. POSA2, Pg. 325:
"Scoped Locking C++ idiom ensures that
a *LOCK* is acquired when control enters
a scope and released automatically
when control leaves the scope,
regardless of the return path from
note that this concept alone is somewhat
less robust/helpful than POSIX cancellation
cleanup handlers; releasing the lock with
associated data left in broken state is not
really helpful.. btw, that is why win32
ABANDONED mutex state is practically
useless and is rather brain damaged
