hello,

I am trying to add a labelname to the Localenvironment tree using a c plugin node. This labelname will be used by the Routetolabelnode to route the message.
I was able to output to the Localenvironment tree using a compute node but am not sure how to access the Localenvironment tree using a c plugin node.

The functionality that i want to accomplish in the plugin node which i have successfully done in a compute node is :

SET OutputLocalEnvironment.Destination.RouterList.DestinationData[1].labelname = OutputLocalEnvironment.Variables.Result.Service;

The questions I have are:
1) How is the Localenvironment tree related to the Root node? Is it a sibling or a child of root?

I tried using cniNextSibling of the output root element but found nothing.

inRootElement = cniRootElement(&rc, message);
outMsg = cniCreateMessage(&rc, cniGetMessageContext(&rc, message));
outRootElement = cniRootElement(&rc, outMsg);
cniCopyElementTree(&rc, inRootElement, outRootElement);
bodySibling = cniNextSibling(&rc, outRootElement);

I tried creating a new element called LocalEnvironment as a sibling of root using

localenv = cniCreateElementAfter(&rc,outRootElement);
cniSetElementType(&rc, localenv, CCI_ELEMENT_TYPE_NAME_VALUE);
cniSetElementName(&rc, localenv, "LocalEnvironment");

but this errored out.

2) So how can I write out to the Localenvironment tree using the c node utility functions?

I understand that the input message has an empty localenvironment tree but I have no way of accessing this through the utility functions that are available.

I tried tracing the output message using the trace node but i don't see the localenvironment output from the c plugin node. When I use the compute node, I do see that the values are being placed in the localenvironment tree.
