| michael@0 | 8 | * |
| michael@0 | 9 | * The purpose of this test and the sproc_ch.c test is to test the shutdown |
| michael@0 | 10 | * of all the IRIX sprocs in a program when one of them dies due to an error. |
| michael@0 | 11 | * |
| michael@0 | 12 | * In this test, the parent sproc gets a segmentation fault and dies. |
| michael@0 | 13 | * The child sproc never stops on its own. You should use "ps" to see if |
| michael@0 | 14 | * the child sproc is killed after the parent dies. |
