I think the issue is whether it _can_ be opened exclusive, right? Not whether it is already open, somewhere, exclusive.

I think a better choice is to either have a choice to not throw an error if EXCLUSIVE fails, or to have your function also use it exclusive if it can. Don't know if that was clear.

Just getting a true from CanOpenExclusive() isn't good enough since it might get used between the function and the next line where you USE it.
