19 * TEST IDENTIFIER : fdatasync02
20 *
21 * EXECUTED BY : Any user
22 *
23 * TEST TITLE : Checking error conditions for fdatasync(2)
24 *
25 * TEST CASE TOTAL : 2
26 *
27 * AUTHOR : Madhu T L <madhu.tarikere@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. fdatasync(2) returns -1 and sets errno to EBADF for invalid
36 * file descriptor.
37 * 2. fdatasync(2) returns -1 and sets errno to EINVAL for file
38 * descriptor to a special file.
39 *
40 * Setup:
41 * Setup signal handling.
42 * Set expected errnos for logging
43 * Pause for SIGUSR1 if option specified.
44 *
45 * Test:
46 * Loop if the proper options are given.
47 * Perform testcase specific setup (if needed)
48 * Execute system call
49 * Check return code and error number, if matching,
50 * Issue PASS message
51 * Otherwise,
52 * Issue FAIL message
53 * Perform testcase specific cleanup (if needed)
54 *
55 * Cleanup:
56 * Print errno log and/or timing stats if options given
57 *
58 * USAGE: <for command-line>
59 * fdatasync02 [-c n] [-e] [-f] [-h] [-i n] [-I x] [-p] [-P x] [-t]
60 * where, -c n : Run n copies concurrently.
61 * -e : Turn on errno logging.
62 * -f : Turn off functional testing
63 * -h : Show help screen
64 * -i n : Execute test n times.
65 * -I x : Execute test for x seconds.
66 * -p : Pause for SIGUSR1 before starting
67 * -P x : Pause for x seconds between iterations.
68 * -t : Turn on syscall timing.
69 *
