Loading shared objects - How? The HyperNews Linux KHG Discussion Pages

Question: Loading shared objects - How?

Forum: The Linux Kernel Hackers' Guide

Does anyone know where I could find a good document about how shared objects are bound to an ELF executable before runtime? I would like to be able to import symbols from a .so file at runtime based on user input and call the imported symbol (a function). I suspect gdb must do this since it loads shared libraries for programs one debugs and allows one to call the imported functions. I hope to do this as portably as possible. Can anyone out there recommend a document?

Thanks.
