[Nadine Chen]

Hi all,
Do you know please what should I write in cc file in order to recuperate an information about a node's attribute:for example my tcl file generates a trace file giving me informations about the remaining energy on each node and I want that this information will be well known in the .CC file but I don't know how?
Please help me.
Thank you so much for your help.
