Wanted: general queue handling library

[Lee McLoughlin]

I am looking for a PUBLIC DOMAIN general queue handling library for
use under Unix.  

It has to be able to handle,
	the queues are held in files so they can be shared
		between programs and exist after any particular
		program has run (so the BDS 4.? insque,remque
		stuff isn't enough)
	mutltiple queues,
	request interlocking,
	dynamic creation/deletion of queues,
	prioritied adding/removal of elements to a queue
	actions should be atomic (or at least resistant to
		the system crashing in the middle of an action).
	allowing the queue elements to be of any type would be
		useful but fixed size at compile would suffice.

Since queue maintenance is a fairly fundamental thing it has always
been suprising to me that there is no such library standardly
available.

	Thanks in advance
