As I work on the new interface, I find myself going toward a separatearg init function for each TCLAP type we implement, each having itsown signature which parrots the TCLAP class. Then the common structis actually initialized behind the scenes. That way we alsopiggy-back on the TCLAP manual for how to use each type.Don't follow and probably won't until your example is complete so I'll defercommenting further.
Okay, the new API is buildable and ready for comment. Note that my
example uses an atexit function to clean up arg memory almost
painlessly (valgrind shows TCLAP C++ memory can still use some work).
Will take some time to digest and review, but can say right off the bat that using atexit() for memory management trades one problem for another. It's fine for main() functions that are only called once, but all of our command API gets called over and over again. It will slowly acquire memory as commands are called and will eventually run out, crash, thrash, etc, or need to be shut down.
Still, that's an easy point to address, just remove it and make the caller release the memory so we're back where we were beforehand. Now that you're done, I'll look and hopefully can see what the issue is with static memory. Stay tuned... ;)
Cheers!
