regarded and expertly designed C++ library projects in the
world.

Gets the non-blocking mode of the socket.
bool non_blocking() const;
true
if the socket's synchronous
operations will fail with boost::asio::error::would_block
if they are unable to perform the requested operation immediately. If
false
, synchronous operations
will block until complete.
The non-blocking mode has no effect on the behaviour of asynchronous
operations. Asynchronous operations will never fail with the error boost::asio::error::would_block
.
