Gets the non-blocking mode of the socket.

bool non_blocking() const;

Return Value

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.

Remarks

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.
