Yes, as you can see if you look at the libibverbs internals, ibv_get_async_event() is just doing read() on a file descriptor. So all the standard ways of handling finding out whether the descriptor is ready to read should work: block in read(), use poll(), epoll, SIGIO, async IO, etc. And using fcntl to set the descriptor to non-blocking mode would work too. - R. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
