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 |
