||
27 | |||
28 | Posix test 2: |
||
29 | |||
30 | pthread_once + thread_specific_data |
||
31 | |||
32 | the main task: |
||
33 | creates a key |
||
34 | creates 2 tasks, J1, J2 |
||
35 | at t = 0.4 sec. it kills J1 and J2 |
||
36 | |||
37 | J1 and J2 will set and check the thread specific data |
||
38 | and when the die, a destructor is called (twice, because the value |
||
39 | is not set to null...) |
||
40 | |||
41 | non standard function used: |
||
42 | cprintf |
||
43 | sys_gettime |
||
44 | keyboard stuffs |
||
45 | sys_end |
||
