Tools for finding unused function declarations?

Question

Whilst refactoring some old code I realised that a particular header file was full of function declarations for functions long since removed from the .cpp file. Does anyone know of a tool that could find (and strip) these automatically?

Answer 1

You could if possible make a test.cpp file to call them all, the linker will flag the ones that have no code as unresolved, this way your test code only need compile and not worry about actually running.
