* 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.
