/*
* NAME
* times02.c
*
* DESCRIPTION
* Testcase to test that times() sets errno correctly
*
* ALGORITHM
* block1: Pass an invalid address as the "tms" structure, and expect
* that times() would return EFAULT.
*
* USAGE: <for command-line>
* times02 [-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 John George
* -Ported
*
* Restrictions
* NONE
