- * 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.
