- * NAME
- * 	getpgid02.c
- *
- * DESCRIPTION
- *	Testcase to check the basic functionality of getpgid().
- *
- * ALGORITHM
- * 	test 1: Does getpgid(-99) and expects ESRCH.
- * 	test 2: Searches an unused pid and expects ESRCH.
- *
- * USAGE:  <for command-line>
- *  getpgid02 [-c n] [-e] [-i n] [-I x] [-P x] [-t]
- *     where,  -c n : Run n copies concurrently.
- *             -e   : Turn on errno logging.
- *             -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
+/*\
+ * [Description]
  *
- * RESTRICTIONS
- *	none
+ * Verify that getpgid(2) fails with errno ESRCH when
+ * pid does not match any process.
