     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.
