basic_socket_acceptor::native_non_blocking (2 of 3 overloads)

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

void native_non_blocking(
    bool mode);

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.

Parameters

mode

If true, the underlying acceptor is put into non-blocking mode and direct system calls may fail with boost::asio::error::would_block (or the equivalent system error).

Exceptions

boost::system::system_error

Thrown on failure. If the mode is false, but the current value of non_blocking() is true, this function fails with boost::asio::error::invalid_argument, as the combination does not make sense.
