Question

Is there any hook to access the names of the functions being called at runtime in Xcode?

I'm just trying to log the names of all the functions that are called during the lifetime of the process. I have the necessary symbols for the application.

I can do it easily in Visual Studio using _penter() and _pexit() functions. But can't find a way to do it on Xcode.

It's a C++ project btw.

I'm using Xcode 3.1.2 on 10.5.8.

Any help is appreciated.

Thanks.
