Subject: [timer] timer_delete function async problem
Hi everrone
Problem:
When I created SIGEV_THREAD timer, then start it by timer_settime. like this
the notify callback in the helper thread 'start' will be run when timer expiration.
But when I delete the timer, the notify callback will be run all the same.
This is not what i want. In actual use, I encountered a problem.
I found that the 'timer_delete' function returns immediately after called.
The timer may not perform the delete action.
In addition, the SIGEV_SIGNAL timer can be deleted after called the function.
So i think the function has different semantics for different types.
Is there a way to implement synchronously ?
Looking forward to your reply.
