Oh, I see, just the symbols that are already exported from the
library.  This doesn't seem like a useful and general interface to the
unwinder.  It's not clear to me that with this interface you could,
for example, duplicate the functionality of the glibc backtrace(),
which doesn't work on some platforms.  However, I don't know what you
are trying to achieve.

Would it be possible to do what you need with libunwind instead?
