Closes the socket opened in UDP.open.
First available in version 3.0 build 2039.
No output parameters.
When this method is called asynchronously, a return object containing the output parameters is passed to the specified callback function.
ssCore.UDP.close( paramsObject [, callbackParamsObject] [, errorParamsObject] );
When this method is called synchronously, a return object containing the output parameters is returned to the caller immediately.
var returnObject = ssCore.UDP.close( paramsObject
If a plugin instance is to be reused, UDP.close must be called before a subsequent call to UDP.open.
UDP.close terminates the event notifications started by a prior call to UDP.recvMsg.
