This code is intended as a demonstration of how the dynamic shared memory and dynamic background worker facilities can be used to establish a group of coooperating processes which can coordinate their activities using the shared memory message queue facility. By itself, the code does nothing particularly interesting: it simply allows messages to be passed through a loop of workers and back to the original process. But it's a useful unit test, in addition to its demonstration value. |
