| * Test pthread_cancelstate |
| * The cancelability state of a newly created thread is PTHREAD_CANCEL_ENABLE. |
| * |
| * STEPS: |
| * 1. Create a thread. |
| * 2. In the thread function, set cancel_flag to 1. |
| * 3. Send out a thread cancel request to the new thread |
| * 4. If the cancel request was honored, the cancel_flag will remain 1. |
| * 5. If not, the thread will continue until the end of execution, cancel_flag will be set to -1 |
| * and,therefore failing the test. |
