+		    stackaddr 		NULL 				Workspace (stack) used by thread is allocated (reserved) by the operating system
+		    stacksize 		NULL 				Workspace size used by thread is determined by the operating system
+		    priority 		0 				Priority of the thread (the lower the priority value, the higher the priority...)
+		    policy 		SCHED_OTHER 			The scheduling policy is determined by the system
+		    inheritsched 	PTHREAD_EXPLICIT_SCHED 		scheduling policy and parameters are not inherited but explicitly defined by the attribute object
+		    guardsize 		PAGESIZE 			size of guard area for a thread's created stack (this area will help determine if the thread has exceeded the total amount of space that was allocated for the thread)
