21 * Test Name: setgroups04
22 *
23 * Test Description:
24 * Verify that, setgroups() fails with -1 and sets errno to EFAULT if the list has an invalid address.
25 *
26 * Expected Result:
27 * setgroups() should fail with return value -1 and set expected errno.
28 *
29 * Algorithm:
30 * Setup:
31 * Setup signal handling.
32 * Pause for SIGUSR1 if option specified.
33 *
34 * Test:
35 * Loop if the proper options are given.
36 * Execute system call
37 * Check return code, if system call failed (return=-1)
38 * if errno set == expected errno
39 * Issue sys call fails with expected return value and errno.
40 * Otherwise,
41 * Issue sys call fails with unexpected errno.
42 * Otherwise,
43 * Issue sys call returns unexpected value.
44 *
45 * Cleanup:
46 * Print errno log and/or timing stats if options given
47 *
48 * Usage: <for command-line>
49 * setgroups04 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
50 * where, -c n : Run n copies concurrently.
51 * -f : Turn off functionality Testing.
52 * -i n : Execute test n times.
53 * -I x : Execute test for x seconds.
54 * -P x : Pause for x seconds between iterations.
55 * -t : Turn on syscall timing.
56 *
