| 25 | |||
| 26 | System termination: |
||
| 27 | |||
| 28 | the main task create J1, J2 and wait until 1 sec., then it calls sys_end |
||
| 29 | and cycles around a task_testcancel |
||
| 30 | |||
| 31 | J1 is a system task that ends at t=1.5 sec. |
||
| 32 | |||
| 33 | J2 is another user task that dies at t= 1.8 sec (it will not die!!!) |
