| * This sample test aims to check the following assertion: |
| * |
| * No atexit() registered routine shall be called because of pthread_exit(). |
| |
| * The steps are: |
| * |
| * -> Create threads with different attributes (but all must be joinable) |
| * -> inside the thread, |
| * -> register a function with atexit() |
| * -> call pthread_exit. |
| * -> In the main thread, we join the thread and check the function did not execute. |
