21 * Test Name : sysinfo02
22 *
23 * Test description
24 * Verify that sysinfo() returns the correct error for an invalid address structure.
25 *
26 * Expected Result :
27 * sysinfo() returns value 0 on success and the sysinfo structure should
28 * be filled with the system information.
29 *
30 * Algorithm:
31 * Setup :
32 * Setup for signal handling.
33 * Create temporary directory.
34 * Pause for SIGUSR1 if option specified.
35 * Test:
36 * Loop if the proper option is given.
37 * Execute the system call.
38 * Pass an invalid address to the structure.
39 * Check return code, if system call failed (return=-1)
40 * Test case passed, Issue functionality pass message
41 * Otherwise,
42 * Issue Functionality-Fail message.
43 * Cleanup:
44 * Print errno log and/or timing stats if options given
45 * Delete the temporary directory created.
46 *
47 * USAGE: <for command-line>
48 * sysinfo02 [-c n] [-i n] [-I x] [-P x] [-t]
49 * where, -c n : Run n copies concurrently.
50 * -i n : Execute test n times.
51 * -I x : Execute test for x seconds.
52 * -P x : Pause for x seconds between iterations.
53 * -t : Turn on syscall timing.
54 * History

58 * Restrictions:
59 * None
