You must never share the same handle in multiple threads. You can pass the
handles around among threads, but you must never use a single handle from
more than one thread at any given time.
Usecase: (cpp)
1. Get a multi handle and post an async req
2. If still_running = 1 push them into a global map
Them?
3. another thread which actively parse this map to select() the handles.
(one thread dedicated for selection for pending request)
Why another thread? The thread in (2) can't do anything anyway as long as (3)
uses the same handle.
4. If an activity is detected another thread from threadpool perform multi
perform.
Yet another? It's still the same multi handle,so it can't do anything with the
handle unless the other threads using the handle all hold off.
So using a proper locking mechanism i understand that i should be able to
perform the above without any exception.
Sure, but the question is then left why you feel you need to use so many
threads...
