22 *    EXECUTED BY	: Anyone
23 *
24 *    TEST TITLE	: Test checking for basic error conditions
25 *    				 for ustat(2)
26 *
27 *    TEST CASE TOTAL	: 2
28 *       $
29 *    AUTHOR		: Aniruddha Marathe <aniruddha.marathe@wipro.com>
30 *
31 *    SIGNALS
32 * 	Uses SIGUSR1 to pause before test if option set.
33 * 	(See the parse_opts(3) man page).
34 *
35 *    DESCRIPTION
36 *	This test case checks whether ustat(2) system call  returns
37 *	appropriate error number for invalid
38 *	dev_t parameter. Next, it checks for bad address paramater.
39 *
40 * 	Setup:
41 *	  Setup signal handling.
42 *	  Pause for SIGUSR1 if option specified.
43 *	  For testing error on invalid parameter, set dev_num to -1
44 *
45 * 	Test:
46 *	  Loop if the proper options are given.
47 *	  Execute system call with invaid flag parameter
48 *	  and then for invalid user
49 *	  Check return code, if system call fails with errno == expected errno
50 *		Issue syscall passed with expected errno
51 *	  Otherwise,
52 *	  Issue syscall failed to produce expected errno
53 *
54 * 	Cleanup:
55 * 	  Do cleanup for the test.
56 * 	 $
57 * USAGE:  <for command-line>
58 *  ustat02 [-c n] [-e] [-i n] [-I x] [-p x] [-t] [-h] [-f] [-p]
59 *  where
60 *  	-c n: run n copies simultaneously
61 *	-e   : Turn on errno logging.
62 *	-i n : Execute test n times.
63 *	-I x : Execute test for x seconds.
64 *	-p   : Pause for SIGUSR1 before starting
65 *	-P x : Pause for x seconds between iterations.
66 *	-t   : Turn on syscall timing.
67 *
68 *RESTRICTIONS: None
