name-mangling

Using gcc, when I ask for an object/variable's type using typeid, I get a different result from the type_info::name method from what I'd expect to get on Windows. I Googled around a bit, and found out that RTTI names are implementation-specific. Problem is, I want to get a type's name as it would be returned on Windows. Is there an easy way to do this? Gregory Pakosz If it's what you're asking, there is no compiler switch that would make gcc behave like msvc regarding the name returned by type_info::name() . However, in your code you can rely on the gcc specific __cxa_demangle function. There

I was writing a decorator that needs to access private variables and found this discrepancy. Can anyone explain this? (Python 2.5) Naming mangling works as expected for attributes defined in the class: >>> class Tester(object): ... __foo = "hi" >>> t = Tester() >>> t._Tester__foo 'hi' Instance attributes do not work (and this is the way we are supposed to do it right?) >>> class Tester(object): ... def __init__(self): ... self.__foo = "hi" >>> t = Tester() >>> t._Tester__foo AttributeError: 'Tester' object has no attribute '_Tester__foo' P.S. Is "class attribute" the right word for these? They

Is there a function in the Python standard library to reproduce Python's name mangling scheme with a "private" attribute name? It seems like there would be, but I can't find it for the life of me. I wrote this, but if there's a better way I'm all ears. def mangle_name (cls, attrname) : prefix = '_' + cls.__name__.lstrip('_') if not attrname.startswith('__') : attrname = '__' + attrname if not attrname.endswith('__') : return prefix + attrname else : return attrname class Foo : __some_such = 3 name = mangle_name(Foo, '__some_such') print name print hasattr(Foo(), name) It looks like the

To undecorate mangled C++ names that Visual Studio generates, you can use undname.exe . But what if you want to avoid the overhead of creating a full-blown process every time you need undecoration? Is there any equivalent functionality in the Visual Studio SDK (should be supported in VS2005)? You're looking for UnDecorateSymbolName function provided by dbghelp. 来源： https://stackoverflow.com/questions/1617204/undecorate-function-names-with-visual-studio-sdk

How do I view the compiler-generated mangled names for overloaded functions in C++? I'm using VC9 but answers for other compilers are welcome too. Edit: I find all the answers useful here. Accepting the one I liked best. You could look in the map file. Assuming you have map file generation turned on. You can see the decorated function names by using Dependency Walker . Open any DLL\EXE in dependency walker and in right pane you can see a list of decorated function names. Since you also ask about other compilers. There is a tool called nm on the gnu toolchain. You will get it on linux and
