| * TEST IDENTIFIER : timer_create04 |
| * |
| * EXECUTED BY : anyone |
| * |
| * TEST TITLE : Test checking for basic error conditions for |
| * timer_create(2) |
| * |
| * TEST CASE TOTAL : 8 |
| * |
| * AUTHOR : Aniruddha Marathe <aniruddha.marathe@wipro.com> |
| * |
| * SIGNALS |
| * Uses SIGUSR1 to pause before test if option set. |
| * (See the parse_opts(3) man page). |
| * |
| * DESCRIPTION |
| * This test case check whether timer_create(2) returns appropriate error |
| * value for invalid parameter |
| * |
| * Setup: |
| * Setup signal handling. |
| * Pause for SIGUSR1 if option specified. |
| * |
| * Test: |
| * Loop if the proper options are given. |
| * For case 7 set event parameter as bad pointer |
| * for case 8 set returned timer ID parameter as bad pointer |
| * Execute system call with invalid parameter |
| * Check return code, if system call fails with errno == expected errno |
| * Issue syscall passed with expected errno |
| * Otherwise, Issue syscall failed to produce expected errno |
| * |
| * Cleanup: |
| * Print errno log and/or timing stats if options given |
| * |
| * USAGE: <for command-line> |
| * timer_create04 [-c n] [-e] [-i n] [-I x] [-P x] [-t] [-p] |
| * where: |
| * -c n : run n copies simultaneously |
| * -e : Turn on errno logging. |
| * -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: |
| * None |
