| * This sample test aims to check the following assertion: |
| * |
| * Once the thread has been created, subsequent changes to the |
| * thread attribute object don't affect the running thread. |
| |
| * The steps are: |
| * -> stack grow |
| * -> create a thread with minimal stack size |
| * -> change the stack size to a bigger value |
| * -> check that the thread stack size did not change. |
| * -> stack decrease |
| * -> create a thread with a known stack size (> minimum) |
| * -> change the stack size to the min value |
| * -> check that the thread stack size did not change. |
| * -> sched policy/param change |
| * -> create a new thread with a known policy |
| * -> change the policy in the thread attribute and check the thread policy did not change |
| * -> change the schedparam in the thread attribute and check the thread priority did not change |
| * -> change the policy in the running thread and check the thread attribute did not change. |
| * -> change the priority in the running thread and check the thread attribute did not change. |
| |
| * The test fails if one of the checking fails |
