Gets the non-blocking mode of the native acceptor implementation.

bool native_non_blocking() const;

This function is used to retrieve the non-blocking mode of the underlying native acceptor. This mode has no effect on the behaviour of the acceptor object's synchronous operations.

Return Value

true if the underlying acceptor is in non-blocking mode and direct system calls may fail with asio::error::would_block (or the equivalent system error).

Remarks

The current non-blocking mode is cached by the acceptor object. Consequently, the return value may be incorrect if the non-blocking mode was set directly on the native acceptor.
