- *
- * TEST IDENTIFIER : sysfs04
- *
- *
- * EXECUTED BY : anyone
- *
- * TEST TITLE : Test checking for basic error conditions
- * for sysfs(2)
- *
- * TEST CASE TOTAL : 1
- *
- * 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.
- *
- * 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
- *
- * 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>
- * sysfs04 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f] [-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:
- *No libc or glibc support
