libghc-concurrent-extra-dev - 0.7.0.12-2+b1 main

The @concurrent-extra@ package offers among other things the
following selection of synchronisation primitives:
.
* @Broadcast@: Wake multiple threads by broadcasting a value.
.
* @Event@: Wake multiple threads by signalling an event.
.
* @Lock@: Enforce exclusive access to a resource. Also known as a
binary semaphore or mutex. The package additionally provides an
alternative that works in the @STM@ monad.
.
* @RLock@: A lock which can be acquired multiple times by the same
thread. Also known as a reentrant mutex.
.
* @ReadWriteLock@: Multiple-reader, single-writer locks. Used to
protect shared resources which may be concurrently read, but only
sequentially written.
.
* @ReadWriteVar@: Concurrent read, sequential write variables.
.
Please consult the API documentation of the individual modules for
more detailed information.

This package was inspired by the concurrency libraries of Java and
Python.
