Sets the non-blocking mode of the native acceptor implementation.
void native_non_blocking( bool mode, asio::error_code & ec);
This function is used to modify the non-blocking mode of the underlying native acceptor. It has no effect on the behaviour of the acceptor object's synchronous operations.
If true
, the underlying acceptor is put into non-blocking
mode and direct system calls may fail with asio::error::would_block
(or the equivalent system error).
Set to indicate what error occurred, if any. If the mode
is false
, but the current value of non_blocking()
is true
, this function fails with asio::error::invalid_argument
,
as the combination does not make sense.
