19 * TEST IDENTIFIER : getrusage02
20 *
21 * EXECUTED BY : anyone
22 *
23 * TEST TITLE : Tests for error conditions
24 *
25 * TEST CASE TOTAL : 2
26 *
27 * AUTHOR : Saji Kumar.V.R <saji.kumar@wipro.com>
28 *
29 * SIGNALS
30 * Uses SIGUSR1 to pause before test if option set.
31 * (See the parse_opts(3) man page).
32 *
33 * DESCRIPTION
34 * Verify that
35 * 1) getrusage() fails with errno EINVAL when an invalid value
36 * is given for who
37 * 2) getrusage() fails with errno EFAULT when an invalid address
38 * is given for usage
39 *
40 * Setup:
41 * Setup signal handling.
42 * Pause for SIGUSR1 if option specified.
43 *
44 * Test:
45 * Loop if the proper options are given.
46 * Execute system call
47 * if call failed with expected errno,
48 * Test Passed
49 * else
50 * Test Failed
51 *
52 * Cleanup:
53 * Print errno log and/or timing stats if options given
54 *
55 * USAGE: <for command-line>
56 * getrusage02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f]
57 * [-p]
58 * where, -c n : Run n copies concurrently.
59 * -e : Turn on errno logging.
60 * -h : Show help screen
61 * -f : Turn off functional testing
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 *
