This directory currently only contains one example for testing process semaphores. proc_sema: This test can be used to test out the named process semaphores support on your platform. It can be run as either a supplier or a consumer process. The available options are: -c: Make us a consumer. -s: Make us a supplier. -x: Remove the semaphore after we're done. -n: Specify the name of the semaphore. -i: Number of acquire/release we'll perform. -d: Delay for # of second before exiting the program You can use this test to see how process semaphores work. For example, run the program as: proc_sema -c -i 10 proc_sema -s -i 3 proc_sema -s -i 7
