Sets the non-blocking mode of the native acceptor implementation.
void native_non_blocking( bool mode, boost::system::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.
true, the underlying acceptor is put into non-blocking
mode and direct system calls may fail with
(or the equivalent system error).
Set to indicate what error occurred, if any. If the
false, but the current value of
true, this function fails with
as the combination does not make sense.
