- * NAME
- * statfs03.c
- *
- * DESCRIPTION
- * Testcase to check that statfs(2) sets errno to EACCES when
- * search permission is denied for a component of the path prefix of path.
- *
- * ALGORITHM
- * Use a component of the pathname, where search permission
- * is denied for a component of the path prefix of path.
- *
- * USAGE: <for command-line>
- * statfs03 [-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
- * 05/2002 Ported by Jacky Malcles
- *
- * RESTRICTIONS
- * NONE
+/*\
+ * [Description]
*
+ * Verify that statfs(2) fails with errno EACCES when search permission
+ * is denied for a component of the path prefix of path.
