nm output explanation

[aaksduid]

Hi, I'm looking for extended information (more than the manpage provides) for the nm command (maybe a tutorial or webpage). Espescially concerning the symbol types. I used "nm library" and got an "?" as symbol type. Can someone explain this?

Regards

"?" The symbol type is unknown, or object file format specific.
