| * 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 a cleanup handler routine, then call pthread_cleanup_pop, setting |
| * 'execution' to a zero value (meaning the cleanup handler shouldn't be executed) |
| * 3. Verify that the cleanup handler was not called. |
