nlist.3: Clarify which symbol table is used

[emaste]

Summary

nlist() currently fetches symbol names only from SHT_SYMTAB.

[kib]

I would also mention that the function uses section headers to look up symtab, which means that a legitimate binary with sections stripped would not work.

[emaste]

Try to clarify sections. I can put in an explicit reference to strip(1) if you think it's worthwhile.

[kib]

I do not believe that strip could remove section headers. It is either linker script or linker which would do that, or some more involved ELF editing tool.
Point is that rtld does not need sections at all.

Oh, yes of course, it's the DT_* tags that rtld cares about.
