|
|
*
|
|
* TEST TITLE : test for checking error conditions for getrlimit(2)
|
|
*
|
|
* TEST CASE TOTAL : 2
|
|
*
|
|
* AUTHOR : Suresh Babu V. <suresh.babu@wipro.com>
|
|
*
|
|
* SIGNALS
|
|
* Uses SIGUSR1 to pause before test if option set.
|
|
* (See the parse_opts(3) man page).
|
|
*
|
|
* DESCRIPTION
|
|
* Verify that,
|
|
* 1) getrlimit(2) returns -1 and sets errno to EFAULT if an invalid
|
|
* address is given for address parameter.
|
|
* 2) getrlimit(2) returns -1 and sets errno to EINVAL if an invalid
|
|
* resource type (RLIM_NLIMITS is a out of range resource type) is
|
|
* passed.
|
|
*
|
|
* 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 and errno set == expected errno
|
|
* Issue sys call fails with expected return value and errno.
|
|
* Otherwise,
|
|
* Issue sys call failed to produce expected error.
|
|
*
|
|
* Cleanup:
|
|
* Print errno log and/or timing stats if options given
|
|
*
|
|
* USAGE: <for command-line>
|
|
* getrlimit02 [-c n] [-e] [-i n] [-I x] [-P x] [-p] [-t] [-h]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on errno logging.
|
|
* -i n : Execute test n times.
|
|
* -I x : Execute test for x seconds.
|
|
* -P x : Pause for x seconds between iterations.
|
|
* -p : Pause for SIGUSR1 before startingt
|
|
* -t : Turn on syscall timing.
|
|
* -h : Display usage information.
