     21  * NAME
     22  *	uname03.c
     23  *
     24  * DESCRIPTION
     25  *	uname03 - call uname() and make sure it succeeds
     26  *
     27  * ALGORITHM
     28  *	loop if that option was specified
     29  *	issue the system call
     30  *	check the errno value
     31  *	  issue a PASS message if we get zero
     32  *	otherwise, the tests fails
     33  *	  issue a FAIL message
     34  *	  break any remaining tests
     35  *	  call cleanup
     36  *
     37  * USAGE:  <for command-line>
     38  *  uname03 [-c n] [-f] [-i n] [-I x] [-p x] [-t]
     39  *	where,  -c n : Run n copies concurrently.
     40  *		-f   : Turn off functionality Testing.
     41  *		-i n : Execute test n times.
     42  *		-I x : Execute test for x seconds.
     43  *		-P x : Pause for x seconds between iterations.
     44  *		-t   : Turn on syscall timing.
