| * This sample test aims to check the following assertions: |
| * |
| * pthread_kill() sends the specified signal to the specified thread. |
| |
| * The steps are: |
| * -> set a signal handler |
| * -> Create a new thread |
| * -> pthread_kill this thread from the main thread |
| * -> Wait that the signal handler is called |
| * -> Check that the correct signal is received in the correct thread |
| |
| * The test fails if a bad signal is received or bad thread receives it. |
