 /*
- * NAME
- *	fsync03.c
- *
- * DESCRIPTION
- *	Testcase to check that fsync(2) sets errno correctly.
- *
- * ALGORITHM
- *	1. Call fsync() with an invalid fd, and test for EBADF.
- *	2. Call fsync() on a pipe(fd), and expect EINVAL.
- *
- * USAGE:  <for command-line>
- *  fsync03 [-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
+ * Test Description:
+ *  Testcase to check that fsync(2) sets errno correctly.
+ *  1. Call fsync() with an invalid fd, and test for EBADF.
