21 * NAME
22 * fsync03.c
23 *
24 * DESCRIPTION
25 * Testcase to check that fsync(2) sets errno correctly.
26 *
27 * ALGORITHM
28 * 1. Call fsync() with an invalid fd, and test for EBADF.
29 * 2. Call fsync() on a pipe(fd), and expect EINVAL.
30 *
31 * USAGE: <for command-line>
32 * fsync03 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
33 * where, -c n : Run n copies concurrently.
34 * -e : Turn on errno logging.
35 * -i n : Execute test n times.
36 * -I x : Execute test for x seconds.
37 * -P x : Pause for x seconds between iterations.
38 * -t : Turn on syscall timing.
39 *
40 * HISTORY
41 * 07/2001 Ported by Wayne Boyer
42 *
43 * RESTRICTIONS
44 * NONE
