Question

In C++, is there a way to get the function signature/name from it’s pointer like this?

void test(float data) {}
cout << typeid(&test).name();

I want to use this data for logging.

Answer 1

If you just want to log the current function name, most of the compilers have __FUNCTION__ macro, which will give you the current function name at compile time.

You may also look for stack walking techniques (here is an example for Windows), which can provide you more information about the current call stack and function names at runtime.
