The naive delevopper will: - close the end of the pipe, but it does not break poll(2), and moreover in multithread context it is not safe due to fd reuse -use timeout but in this case why use poll...
The goal is also to shutdown an eventfd but without kernel support, I suppose it is not possible... Bastien > > > > > for getting outside poll. > > I don't understand what you mean here. > > Bruno >
