[Boost-users] Non-blocking i/o using ASIO socket

Hello all, Can you please advise where we need to use "non_blocking_io" flag in ASIO sockets. IIUC, we can do the same using all of the async_xxxx functions provided in the various socket classes. Does it mean that if we do not wish to use ioservice::post() mechanism, we have the option to use "non_blocking_io" flag and implement async functionality? Thanks, Vikas
