| 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. |
