|
* TEST TITLE : Test checking for basic error conditions
|
|
* for sysfs(2)
|
|
*
|
|
* TEST CASE TOTAL : 3
|
|
*
|
|
* AUTHOR : Aniruddha Marathe <aniruddha.marathe@wipro.com>
|
|
*
|
|
* SIGNALS
|
|
* Uses SIGUSR1 to pause before test if option set.
|
|
* (See the parse_opts(3) man page).
|
|
*
|
|
* DESCRIPTION
|
|
* This test case checks whether sysfs(2) system call returns
|
|
* appropriate error number for invalid
|
|
* option and for invalid filesystem name.
|
|
*
|
|
* Setup:
|
|
* Setup signal handling.
|
|
* Pause for SIGUSR1 if option specified.
|
|
*
|
|
* Test:
|
|
* Loop if the proper options are given.
|
|
* Execute system call with invaid option parameter and for
|
|
* invalid filesystem name
|
|
* Check return code, if system call fails with errno == expected errno
|
|
* Issue syscall passed with expected errno
|
|
* Otherwise,
|
|
* Issue syscall failed to produce expected errno
|
|
*
|
|
* Cleanup:
|
|
* Do cleanup for the test.
|
|
*
|
|
* USAGE: <for command-line>
|
|
* sysfs05 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-f] [-h] [-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.
|
|
*
|
|
*RESTRICTIONS:
|
|
*There is no libc or glibc support
|
|
*Kernel must be compiled with ext2 support
|
