Quick LibELF Guide

Libelf is great, I use it a lot. Its multi platform, well written, the license is LGPL, and the author answers questions quickly. But the documentation just isn't there. I get a lot of hits to this blog when people search google on libelf topics. So I thought a good blog entry on how to use libelf would be beneficial to others. Below is a link to heavily commented C code on using libelf to read the sections and symbols of an ELF object.

Libelf Example in C

It's an example of how to read an ELF objects section header and symbol table. Ill leave relocation reading as an exercise for the reader.
