Closes the port, and releases its resources.
The port has been successfully destroyed.
The port is not valid (either CreateClient has not been called or DestroyClient / ClosePort has already been called).
An exception occurred while processing the request.
Each open port requires one license. For this reason, you should close every port as soon as it is no longer needed.
This method has been deprecated in favor of DestroyClient and will be removed from future releases.
