| 7 * Test sproc_ch.c | |
| 8 * | |
| 9 * The purpose of this test and the sproc_p.c test is to test the shutdown | |
| 10 * of all the IRIX sprocs in a program when one of them dies due to an error. | |
| 11 * | |
| 12 * There are three sprocs in this test: the parent, the child, and the | |
| 13 * grandchild. The parent and child sprocs never stop on their own. | |
| 14 * The grandchild sproc gets a segmentation fault and dies. You should | |
| 15 * You should use "ps" to see if the parent and child sprocs are killed | |
| 16 * after the grandchild dies. | |
