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