 * NAME
 *      fstatat01.c
 *
 * DESCRIPTION
 *	This test case will verify basic function of fstatat64/newfstatat
 *	added by kernel 2.6.16 or up.
 *
 * USAGE:  <for command-line>
 * fstatat01 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p]
 * where:
 *      -c n : Run n copies simultaneously.
 *      -e   : Turn on errno logging.
 *      -i n : Execute test n times.
 *      -I x : Execute test for x seconds.
 *      -p   : Pause for SIGUSR1 before starting
 *      -P x : Pause for x seconds between iterations.
 *      -t   : Turn on syscall timing.
 *
 * Author
 *	Yi Yang <yya...@cn...>

 *      08/24/2006      Created first by Yi Yang <yya...@cn...>
