/*
* Test Name: setgroups04
*
* Test Description:
* Verify that, setgroups() fails with -1 and sets errno to EFAULT if the list has an invalid address.
*
* Expected Result:
* setgroups() should fail with return value -1 and set expected errno.
*
* Algorithm:
* Setup:
* Setup signal handling.
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* Execute system call
* Check return code, if system call failed (return=-1)
* if errno set == expected errno
* Issue sys call fails with expected return value and errno.
* Otherwise,
* Issue sys call fails with unexpected errno.
* Otherwise,
* Issue sys call returns unexpected value.
*
* Cleanup:
* Print errno log and/or timing stats if options given
*
* Usage: <for command-line>
* setgroups04 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
* where, -c n : Run n copies concurrently.
* -f : Turn off functionality Testing.
* -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
* 05/2002 Ported by André Merlier
*
* RESTRICTIONS:
* none.
