I'm writing utility for ELF files processing.
And if I planing to handle only one SYMTAB, things are simpler.
But just want to be sure.
I found here http://www.sco.com/developers/gabi/latest/ch4.sheader.html
... that in case of SHT_REL section, sh_link contain "The section header
index of the associated symbol table."
That disappointing me. Is it rudiment?
