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.
45 *
