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.
