setOption
Sets the value of an integer-valued option on @socket, as with setsockopt(). (If you need to set a non-integer-valued option, you will need to call setsockopt() directly.)
The networking.html header pulls in system headers that will define most of the standard/portable socket options. For unusual socket protocols or platform-dependent options, you may need to include additional headers.
Return
success or failure. On failure, @error will be set, and the system error value (errno or WSAGetLastError()) will still be set to the result of the setsockopt() call.

Parameters
