Shared Library Discovery

Question

I am using C++ on Linux. I want to dynamically bind a collection of unknown shared libraries. I need my code to detect all the public functions exposed by the shared library and the string names of those functions. How do I accomplish this task?

Answer 1

AFAIK, there is no glibc function to enumerate all the public interface functions for a .so file. You can refer to libelf to read all symbols from a dynamic file. Libelf is here http://www.mr511.de/software/. After you find a symbol, you can use dlopen and dlsym to load it.
