##### basic_socket_acceptor::non_blocking (2 of 3 overloads)

Sets the non-blocking mode of the acceptor.

    void non_blocking(
        bool mode);

###### Parameters

mode

  If `true`, the acceptor'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.

###### Exceptions

boost::system::system_error

  Thrown on failure.

###### 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`.
