|
* TEST IDENTIFIER : getrusage02
|
|
*
|
|
* EXECUTED BY : anyone
|
|
*
|
|
* TEST TITLE : Tests for error conditions
|
|
*
|
|
* TEST CASE TOTAL : 2
|
|
*
|
|
* AUTHOR : Saji Kumar.V.R <saji.kumar@wipro.com>
|
|
*
|
|
* SIGNALS
|
|
* Uses SIGUSR1 to pause before test if option set.
|
|
* (See the parse_opts(3) man page).
|
|
*
|
|
* DESCRIPTION
|
|
* Verify that
|
|
* 1) getrusage() fails with errno EINVAL when an invalid value
|
|
* is given for who
|
|
* 2) getrusage() fails with errno EFAULT when an invalid address
|
|
* is given for usage
|
|
*
|
|
* Setup:
|
|
* Setup signal handling.
|
|
* Pause for SIGUSR1 if option specified.
|
|
*
|
|
* Test:
|
|
* Loop if the proper options are given.
|
|
* Execute system call
|
|
* if call failed with expected errno,
|
|
* Test Passed
|
|
* else
|
|
* Test Failed
|
|
*
|
|
* Cleanup:
|
|
* Print errno log and/or timing stats if options given
|
|
*
|
|
* USAGE: <for command-line>
|
|
* getrusage02 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-h] [-f]
|
|
* [-p]
|
|
* where, -c n : Run n copies concurrently.
|
|
* -e : Turn on errno logging.
|
|
* -h : Show help screen
|
|
* -f : Turn off functional testing
|
|
* -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.
|
|
*
