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