26 | ------------ |
||
27 | |||
28 | Posix test 1: |
||
29 | |||
30 | the main task create 4 tasks, J1, J2, J3, J4 |
||
31 | at t = 0.2 sec. it raise a signal to J1 |
||
32 | at t = 0.4 sec. it raise a signal to J2 |
||
33 | at t = 0.8 sec. it kill J4 |
||
34 | |||
35 | J1: it simply calls sigwait |
||
36 | |||
37 | J2: it simply calls sigwaitinfo |
||
38 | |||
39 | J3: it simply calls sigtimedwait with a timeout of 0.5 sec. |
||
40 | |||
41 | J4: it simply calls sigtimedwait with a -long- timeout |
||
42 | (J4 will be killed by main) |
||
43 | |||
44 | non standard function used: |
||
45 | cprintf |
||
46 | sys_gettime |
||
47 | keyboard stuffs |
||
48 | sys_end |
||
