| 28 | Posix test 4: |
||
| 29 | |||
| 30 | the main task create 3 tasks, J1, J2, J3 |
||
| 31 | at t = 1 sec. it raise a signal to J1 |
||
| 32 | at t = 2 sec. it kills J2 |
||
| 33 | |||
| 34 | J1,J2,J3: it simply calls nanosleep |
||
| 35 | |||
| 36 | non standard function used: |
||
| 37 | cprintf |
||
| 38 | sys_gettime |
||
| 39 | keyboard stuffs |
||
| 40 | sys_end |
