unwind(8) uses it and it works fine. https://man.openbsd.org/unwind.8 Have a look at https://github.com/openbsd/src/blob/master/sbin/unwind/resolver.c for inspiration on how to use it. check_resolver() on line 979 might be a good starting point. > > Best regards, Wouter > -- I'm not entirely sure you are real.
