SimpleProducerConsumer

Description

This sample builds two applications:

• The consumer application opens a memory address that is shared between the RTX64 subsystem and windows. The program reads the shared memory address and then sets a globally named event to report that it has completed reading the data. The program will end when a TERMINATE_EVENT is signaled.
• The producer application creates and writes to a globally named shared memory address. The program writes the shared memory address and then sets a globally named event to report it has completed writing the data. The program will run for a set amount of iterations and then set a TERMINATE_EVENT. Outside of the loop it will report on the performance of each exchange.
