posix::basic_stream_descriptor::non_blocking (3 of 3 overloads)

Inherited from posix::basic_descriptor.

Sets the non-blocking mode of the descriptor.

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

mode

If true, the descriptor'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.
