/*
 * Test Name :	sysinfo02
 *
 * Test description
 *  Verify that sysinfo() returns the correct error for an invalid address structure.
 *
 * Expected Result :
 *  sysinfo() returns value 0 on success and the sysinfo structure should
 *  be filled with the system information.
 *
 * Algorithm:
 *  Setup :
 *   Setup for signal handling.
 *   Create temporary directory.
 *   Pause for SIGUSR1 if option specified.
 * Test:
 *  Loop if the proper option is given.
 *  Execute the system call.
 *  Pass an invalid address to the structure.
 *  Check return code, if system call failed (return=-1)
 *	Test case passed, Issue functionality pass message
 *  Otherwise,
 *	Issue Functionality-Fail message.
 * Cleanup:
 *  Print errno log and/or timing stats if options given
 *  Delete the temporary directory created.
 *
 * USAGE:  <for command-line>
 *	sysinfo02 [-c n] [-i n] [-I x] [-P x] [-t]
 *	where,  -c n : Run n copies concurrently.
 *		-i n : Execute test n times.
 *		-I x : Execute test for x seconds.
 *		-P x : Pause for x seconds between iterations.
 *		-t   : Turn on syscall timing.
 * History
 *	07/2001 John George
 *		-Ported
 *
 * Restrictions:
 *  None
