You have a point, pd crashing some time or another is inevitable, and even 'force quitting' the example app given to me by a the Wacom guys has the same problem as I am dealing with - with one difference in that restarting their app will reset the driver to its original state. I must still be missing something in my attempts.
One thing I still wonder about; why is shutting pd via Ctrl-q any different than closing a patch (causing an exit() before destroying the patches)? [closebang]'s won't work either, I suppose, among other things like what I am trying to do.

Okay, so Ctrl-Q skips all free functions on purpose. If I am
understanding correctly, I need to register my cleanup function with atexit on a function of type void _function_(void), but that means I don't have access to any of my object's member variables.
one workaround is to make a global map<MyClass,int> where int is a dummy (unfortunately, void is not accepted as an argument of that type-pattern).
In the case of flext, the external class would need to be declared as
static in order for its destructor to be called before shutting down - do you know if this is right, or possible, Thomas or anyone else knowing about flext/C++ and pd?
This doesn't sound right. Note that there are some things that apply to objects that are directly global, and don't apply when the global variables are just pointers. I almost always use the latter because the former is a pain in the ass. (any static variable counts as global in this case, because they're essentially a kind of hidden global).
The reason I need this is because I am messing around with disconnecting
the wacom events from controlling the tablet, which takes some calls that change the driver's settings. If I cannot turn the settings back before the program stops, they are permanently screwed until I restart the driver/computer. At least, this is all I can tell so far.
ow. so what can it do in case of segmentation fault or other crash of Pd?... what happens if you bang a naked [until] while you use your wacom thing?
