C++ : Finding out decorated names
How can I find out the decorated name that will be asigned to each method name ? I'm trying to find out what the decorated name is , so that I may export it , in a DLL .
Answer
.DEF file are still being used?
Forget .DEF files. They are a thing of the past.
Export your functions, be them C functions or C++ symbols, through __declspec(dllimport/dllexport).
If you really need undecorated names, use as suggested by Greg Hewgill, the __declspec(dllimport/dllexport) keywords, combined with extern "C", which will strip those symbols of their decoration...
Are you sure you want to remove the C++ decoration?
There are some valid reasons for that: You want to export code that will be used by C code, or you want to use your DLL from modules compiled with different compilers.
And for the second reason, I would instead produce one DLL per compiler, and keep the decorations.
Aside those reasons, why do you want the decorations removed?
C++ decorations/name mangling is not Evil
Quite the contrary.
If you are working with one compiler (and I suppose you do, because your want to use the decorated names, not extern "C" ones), then keep the C++ decoration/name mangling.
In this way, you'll be able to use full C++ power, that is, namespaces, classes, function/method overloads, etc..
Still, playing manually with symbol decorations is a recipe for disaster: Use dllexport to export your symbols without having to deal with yet another (.DEF) file.
