| * void pthread_cleanup_pop(int execution); |
| * |
| * Shall remove the routine at the top of the calling thread's cancelation cleanup stack and |
| * optionally invoke it (if execute is non-zero). |
| * |
| * STEPS: |
| * 1. Create a thread |
| * 2. The thread will push 3 cleanup handler routines, then it will call the pop function 3 |
| * times. |
| * 3. Verify that the cleanup handlers are popped in order. |
