Parameters

io_control_code	An int32 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.
