| 24 | ------------ |
||
| 25 | |||
| 26 | Test Number 15 (F): |
||
| 27 | |||
| 28 | This test verify the correctness of the PI module. |
||
| 29 | |||
| 30 | |||
| 31 | the main task (NRT) lock a PI mutex. |
||
| 32 | then 2 tasks arrives, with priority higher than the main |
||
| 33 | |||
| 34 | the first try to lock the mutex, but it can't, so the main inherit |
||
| 35 | his priority. The second simply prints a string. |
||
| 36 | |||
| 37 | If all works, the string of the second task is printed after the end of |
||
| 38 | the first task. |
