This function was removed from the Gateway entirely as it is potentially harmful. It is only present in Gateway versions 7.9.0 - 7.9.3. It is not present in any prior or later versions of Ignition. This function is replaced by system.util.sendRequest(), which provides the same functionality in a more secure implementation. If you are using this function, it is highly recommended that you upgrade to at least 7.9.3 and use system.util.sendRequest() instead.


Invokes a function on the gateway. It will return the return value of the function, or throw an exception if something went wrong calling that function.
