+ * NAME
+ * setrlimit02.c
+ *
+ * DESCRIPTION
+ * Testcase to test the different errnos set by setrlimit(2) system call.
+ *
+ * USAGE: <for command-line>
+ * setrlimit02 [-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
+ *
+ * RESTRICTIONS
+ * NONE
