* Basic test for timer_create(2):
|
|
*
|
|
* Creates a timer for each available clock using the
|
|
* following notification types:
|
|
* 1) SIGEV_NONE
|
|
* 2) SIGEV_SIGNAL
|
|
* 3) SIGEV_THREAD
|
|
* 4) SIGEV_THREAD_ID
|
|
* 5) NULL
|

*
|
|
* This is also regression test for commit:
|
|
* f18ddc13af98 ("alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP")
