basic_socket::non_blocking (3 of 3 overloads)

Sets the non-blocking mode of the socket.

boost::system::error_code non_blocking(
    bool mode,
    boost::system::error_code & ec);

Parameters

mode: If true, 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.
ec: Set to indicate what error occurred, if any.

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.
