  Irrespective of where the variable/function is defined?

Ex.: say an application uses standard library functions/C++ classes like malloc, strncpy, strcmp, operator>>, operator<< etc.

The dwarf DIE of such symbols in the application object file will have DW_AT_external set, I guess, right?

Is there a way to know whether the function is defined in the same compilation unit or is there because of linking with the other compilation units?

Thank you.
