1 | /* Test_task |
---|
2 | * |
---|
3 | * This task initializes the signal catcher, sends the first signal |
---|
4 | * if running on the first node, and loops while waiting for signals. |
---|
5 | * |
---|
6 | * NOTE: The signal catcher is not reentrant and hence RTEMS_NO_ASR must |
---|
7 | * be a part of its execution mode. |
---|
8 | * |
---|
9 | * Input parameters: |
---|
10 | * argument - task argument |
---|
11 | * |
---|
12 | * Output parameters: NONE |
