This question is a continuation of the following question, where a code to demangle a function-name given by the backtrace function is presented.
I wonder whether there is a way to get the name and the namespaces of a callable object. Here we assume that the function does have a name and that it is possible to demangle its name with abi::__cxa_demangle (for example, it's not a lambda function).
Furthermore, would it be possible to get a list of the namespaces in which the function is?
