My leaky memory says we moved entry-point into some form of debug record in the standard libraries, circa Solaris 8/9.
Before that, my group maintained text files that listed all the entry-points and their parameters for libraries like libc.so, so that we could print out parameter values in apptrace(8). There's a (small) chance the records are complete enough that dtrace could use the debug records from the system libraries, and in principle any library with the right information available. I *don't* know whether they are complete enough: that was done after my time in the ABI team. --dave Jon Haslam <jonathan.has...@sun.com> wrote: > Yes, having user-land type information would allow you > to do what you want here.
