    I have a question for the net: how would one go about writing a C
  function that would give you a stack trace of all calls to that
  function?  Ie. about the same kind of output that you might get from
  doing a core dump at that point in the program and typing 'where'
  under dbx?  I'd like to do this several times in a running image, so
  I don't want to actually cause the core dump.  Any ideas?

    I'm running under Sun OS 3.4, but I would think that this kind of
  program could be used in outline on several different types of Unix
  systems.
