| Assumption: The test assumes that this program is run under normal conditions, |
| and not when the processor and other resources are too stressed. |
| |
| This program checks to see that sigsuspend does not return when sent a signal |
| whose action is to terminate the process. |
| |
| Steps: |
| 1. Fork() a child. |
| 2. Have the parent give the child a 1 second headstart. Have the child suspend itself. |
| 3. Have the parent send the child a SIGABRT signal. The default action associated with SIGABRT |
| is to terminate the program. sigsuspend() should not return, and if it does, then have the |
| child return a to the parent with 1 or 2. |
| 4. From the parent, verify that the child neither returns 1 or 2. |
