Global Variable reentrant or not? (Conflicting information)

[Ben]

I had to go back to that thread I linked above to re-read "The Official Word" and I believe the answer is....

"global read writes are reentrant" but writing is protected by a mutex.

Thanks guys, I think I understand. I see how they are bad in certain applications. I believe my confusion is/was in the fact that it is the code that can make it re-entrant.

As I understand it Functional Globals will still give you determinism in RT applications, unless you do what it is explained in the second link I posted (i.e. http://zone.ni.com/devzone/cda/tut/p/id/4338)
