| 26 | Test Number 5: |
||
| 27 | |||
| 28 | this test is a simple main() function with one other task |
||
| 29 | |||
| 30 | This test has to be compiled with init1.c, that introduce 2 RR levels |
||
| 31 | with a timeslice of 300us (!) |
||
| 32 | |||
| 33 | This test can be useful to test functions like |
||
| 34 | |||
| 35 | sigemptyset |
||
| 36 | sigaddset |
||
| 37 | hartik_deliver_pending_signals |
||
| 38 | sys_end |
||
| 39 | task_sigmask |
||
| 40 | sigaction |
||
| 41 | sigqueue |
||
| 42 | task_signal |
