- *
- * TEST IDENTIFIER : sysfs01
- *
- * EXECUTED BY : anyone
- *
- * TEST TITLE : Basic test 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 is a Phase I test for the sysfs(2) system call.
- * This test is carried out for option 1 for sysfs(2).
- * It is intended to provide a limited exposure of the system call.
- *
- *
- * Setup:
- * Setup signal handling.
- * Pause for SIGUSR1 if option specified.
- *
- * Test:
- * Loop if the proper options are given.
- * Execute system call
- * Check return code, if system call failed (return=-1)
- * Log the errno and Issue a FAIL message.
- * Otherwise, Issue a PASS message.
- *
- * Cleanup:
- * Print errno log and/or timing stats if options given
- *
- * USAGE: <for command-line>
- * sysfs01 [-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:
- *There is no glibc or libc support
- *Kernel should be compiled with proc filesystem support
