| * NAME |
| * kill06.c |
| * |
| * DESCRIPTION |
| * Test case to check the basic functionality of kill() when killing an |
| * entire process group with a negative pid. |
| * |
| * ALGORITHM |
| * call setup |
| * loop if the -i option was given |
| * fork 5 children |
| * execute the kill system call |
| * check the return value |
| * if return value is -1 |
| * issue a FAIL message, break remaining tests and cleanup |
| * if we are doing functional testing |
| * if the processes were terminated with the expected signal. |
| * issue a PASS message |
| * otherwise |
| * issue a FAIL message |
| * call cleanup |
| * |
| * USAGE |
| * kill06 [-c n] [-f] [-i n] [-I x] [-P x] [-t] |
| * where, -c n : Run n copies concurrently. |
| * -f : Turn off functionality Testing. |
| * -i n : Execute test n times. |
| * -I x : Execute test for x seconds. |
| * -P x : Pause for x seconds between iterations. |
| * -t : Turn on syscall timing. |
| * |
| * HISTORY |
| * 07/2001 Ported by Wayne Boyer |
| * |
| * RESTRICTIONS |
| * This test should be run as a non-root user. |
