|
|
*
|
|
* TEST TITLE : Basic test for mlockall(2)
|
|
*
|
|
* TEST CASE TOTAL : 3
|
|
*
|
|
* AUTHOR : Nirmala Devi Dhanasekar <nirmala.devi@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 mlockall(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.
|
|
*
|
|
* 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>
|
|
* mlockall01 [-c n] [-e] [-i n] [-I x] [-p x] [-t]
|
|
* where,$
|
|
* -c n : Run n copies concurrently
|
|
* -e : Turn on errno logging.
|
|
* -h : Show this 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.
|
|
*
|
|
* RESTRICTIONS
|
|
* Must run as root.
