| * TEST IDENTIFIER : sched_rr_get_interval03 |
| * |
| * EXECUTED BY : root / superuser |
| * |
| * TEST TITLE : Tests for error conditions |
| * |
| * TEST CASE TOTAL : 3 |
| * |
| * 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) sched_rr_get_interval() fails with errno set to EINVAL for an |
| * invalid pid |
| * 2) sched_rr_get_interval() fails with errno set to ESRCH if the |
| * process with specified pid does not exists |
| * 2) sched_rr_get_interval() fails with errno set to EFAULT if the |
| * address specified as &tp is invalid |
| * |
| * Setup: |
| * Setup signal handling. |
| * Set expected errors for logging. |
| * Pause for SIGUSR1 if option specified. |
| * Change scheduling policy to SCHED_RR |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * Execute system call |
| * if call fails with expected errno, |
| * Test passed. |
| * Otherwise |
| * Test failed |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * sched_rr_get_interval03 [-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. |
