- * Test Name: setgroups03
- *
- * Test Description:
- *  Verify that,
- *   1. setgroups() fails with -1 and sets errno to EINVAL if the size
- *      argument value is > NGROUPS
- *   2. setgroups() fails with -1 and sets errno to EPERM if the
- *	calling process is not super-user.
- *
- * Expected Result:
- *  setgroups() should fail with return value -1 and set expected errno.
- *
- * Algorithm:
- *  Setup:
- *   Setup signal handling.
- *   Pause for SIGUSR1 if option specified.
+/*\
+ * [Description]
  *
- *  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.
+ * Test for EINVAL, EPERM, EFAULT errors.
  *
- *  Cleanup:
- *   Print errno log and/or timing stats if options given
+ * 1) setgroups() fails with EINVAL if the size argument value is > NGROUPS.
  *
- * Usage:  <for command-line>
- *  setgroups03 [-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
- *	07/2001 Ported by Wayne Boyer
- *
- * RESTRICTIONS:
- *  This test should be executed by 'non-super-user' only.
+ * 2) setgroups() fails with EPERM if the calling process is not super-user.
  *
+ * 3) setgroups() fails with EFAULT if the list has an invalid address.
