name mangling

I was just wondering what the easiest way to figure out how a function
gets name mangled in VC++ is.

I have this function:

class Test
{

int operator[](unsigned int index);
};

I'm trying to figure out how this gets mangled in VC++ 6.0 and VS
2005.

Any help is appreciated.

Thank you.

I can't answer, but I'm curious why you care. Are you trying to link object
files compiled by different compilers?

In order to figure out mangled name you need to compile the
code. There is no other way I'm aware of. You can infer some
decoration rules from this MSDN article:

"Format of a C++ Decorated Name"
http://msdn2.microsoft.com/en-us/library/2ax8kbk1(vs.80).aspx

However, a lot of info is internal to comiler/linker and may
take considerable effort to discover via reverse
engineering.

On the other hand, if you need to restore original name from
a mangled one, then there is UndName.exe tool, which is part
of VC++. Also, you can use `UnDecorateSymbolName' function
from DbgHelp.dll library.

... but be aware that it's incomplete - it doesn't cover template names.
