Can “nm” determine whether the undefined symbol is a function or a variable?












1















Is it possible to distinguish whether a symbol reported by nm is a function symbol or a variable symbol?



For example, if nm reports that there is an undefined symbol



U the_undefined_symbol


How can I know whether the_undefined_symbol is an undefined function or an undefined variable?

  • "U" - The symbol is undefined. That is all the documentation says about U symbols. Could you please provide more information?
