Communicating between wow client <> external

[Cypher]

Sure they can, or at least they can store data.
Think of Auctioneer databases etc

The data storage methods WoW expose are useless for exposing data to an external application, because I'm pretty sure the data on disk is only updated when the user reloads the UI, logs out, etc. You can't just read and write 'on the fly'.

If this is incorrect I withdraw my objection, but I'm pretty sure I'm correct.

You are correct. If you want to force a save, you have to indeed reload the ui (/console reloadui) to 'flush' it to the hd.

I'm using an LUA gui to control my application.

First I create a CVar at a specified location in memory,
then use my LUA addon to write to that CVar. i.e. set_FreeCam = 1;

My main app cycles through all of the memory locations I feed it looking for updates, executes the necessary function and resets the CVar to a base value.

Fair enough, I've never actually looked into LUA. I just assumed based off evidence of Auctioneer etc. 'Research' into file writing in LUA addons didn't extend beyond ... well it didn't start, so I stand rightly corrected.
