|
|
* EXECUTED BY : Any user
|
|
*
|
|
* TEST TITLE : Basic test for fdatasync(2)
|
|
*
|
|
* TEST CASE TOTAL : 1
|
|
*
|
|
* AUTHOR : Madhu T L <madhu.tarikere@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 fdatasync(2) system call.
|
|
* It is intended to provide a limited exposure of the system call.
|
|
*
|
|
* Setup:
|
|
* Setup signal handling.
|
|
* Pause for SIGUSR1 if option specified.
|
|
* Create a temp directory and cd to it
|
|
* Initialize filename and open it in write mode for each child process.
|
|
*
|
|
* Test:
|
|
* Loop if the proper options are given.
|
|
* Execute system call
|
|
* Check return code, if system call failed (return=-1)
|
|
* Issue FAIL message with errno.
|
|
* Otherwise, Issue PASS message.
|
|
*
|
|
* Cleanup:
|
|
* Print errno log and/or timing stats if options given
|
|
* Remove temporary directory and all files in it.
|
|
*
|
|
* USAGE: <for command-line>
|
|
* fdatasync01 [-c n] [-e] [-f] [-h] [-i n] [-I x] [-p] [-P x] [-t]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on errno logging.
|
|
* -f : Turn off functional testing
|
|
* -h : Show help screen
|
|
* -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.
|
|
*
