+** Source Code: main.c and semaphore.c
+** main.c creates process and waits for all processes to get over
+** semaphore.c creates a semaphore and then calls threads which will contend for the semaphore
+**
+** This test is for Object Management Test case for semaphore where Object type is shareable.
+** Algorithm
+** o Main Process Creates OBJECT_TYPE Object
+** o Create PROCESS_COUNT processes aware of the Shared Object
