I've finally gotten my -finstrument-functions hack working with dladdr(), but I've noticed that I'm getting a fair amount of garbage out of it. Basically, I'm calling it like so:
You're not checking the return value of dladdr, so there is no way to tell if dladdr is actually returning that value or not. My guess is that it is not setting the function name at all and is returning zero. -- Brian Mastenbrook brian@mastenbrook.net http://brian.mastenbrook.net/
