| michael@0 | 8 | * |
| michael@0 | 9 | * The purpose of this test and the sproc_p.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 | * There are three sprocs in this test: the parent, the child, and the |
| michael@0 | 13 | * grandchild. The parent and child sprocs never stop on their own. |
| michael@0 | 14 | * The grandchild sproc gets a segmentation fault and dies. You should |
| michael@0 | 15 | * You should use "ps" to see if the parent and child sprocs are killed |
| michael@0 | 16 | * after the grandchild dies. |
