21 * NAME
22 * kill01.c
23 *
24 * DESCRIPTION
25 * Test case to check the basic functionality of kill().
26 *
27 * ALGORITHM
28 * call setup
29 * loop if the -i option was given
30 * fork a child
31 * execute the kill system call
32 * check the return value
33 * if return value is -1
34 * issue a FAIL message, break remaining tests and cleanup
35 * if we are doing functional testing
36 * if the process was terminated with the expected signal.
37 * issue a PASS message
38 * otherwise
39 * issue a FAIL message
40 * call cleanup
41 *
42 * USAGE
43 * kill01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
44 * where, -c n : Run n copies concurrently.
45 * -f : Turn off functionality Testing.
46 * -i n : Execute test n times.
47 * -I x : Execute test for x seconds.
48 * -P x : Pause for x seconds between iterations.
49 * -t : Turn on syscall timing.
50 *
51 * HISTORY
52 * 07/2001 Ported by Wayne Boyer
53 *
54 * RESTRICTIONS
55 * This test should be ran as a non-root user.
