Finding Dll Function Parameters
How can I find the parameters of an undocumented Dll function?
I have searched all over the internet and ended up finding one way: it involves decorated functions. However, I cannot find a way to get those.
Any help would be appreciated.

Do C++ mangled names stay consistent when compiled on different computers?
In general, what I've observed using nm on Linux is that T symbol names (which I'm interested in) stay consistent across different computers even when I'm not using extern "C". Is my observation correct?
Note I'm using gcc on all computers.

Is C++ name mangling (decoration) deterministic?
I hope to LoadLibrary on an unmanaged C++ DLL with managed code, and then call GetProcAddress on extern functions which have been mangled. My question is are the mangled names you get from a C++ compiler deterministic? That is: Will the name always…
