size_t xtd::net::sockets::socket::io_control	(	xtd::net::sockets::io_control_code	io_control_code,
		std::vector< xtd::byte > &	option_in_value,
		std::vector< xtd::byte > &	option_out_value
	)

Sets low-level operating modes for the xtd::net::sockets::socket using xtd::net::sockets::io_control_code control codes.

Parameters

io_control_code	A xtd::net::sockets::io_control_code value that specifies the control code of the operation to perform.
option_in_value	A byte array that contains the input data required by the operation.
option_out_value	A byte array that contains the output data returned by the operation.

Returns

The number of bytes in the option_out_value parameter.

Remarks

The xtd::net::sockets::socket::io_control method provides low-level access to the operating system xtd::net::sockets::socket underlying the current instance of the xtd::net::sockets::socket class.

Note

If you receive a xtd::net::sockets::socket_exception, use the xtd::net::sockets::socket_exception xtd::net::sockets::socket_exception::error_code property to obtain the specific error code. After you have obtained this code, refer to the Windows Sockets version 2 API error code documentation for a detailed description of the error.
