| * TEST IDENTIFIER : sched_get_priority_max02 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : Test for error conditions |
| * |
| * TEST CASE TOTAL : 1 |
| * |
| * 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 given an invalid scheduling policy, |
| * sched_get_priority_max() returns -1 with errno EINVAL |
| * |
| * 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) & errno=EINVAL |
| * Test Passed |
| * Otherwise |
| * Test Failed |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * sched_get_priority_max02 [-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. |
