export function name for DLL

[ceodav]

Hello,
i started a DLL project (my first) in VC++8.
Visual studio added autoamtically a class whose publi methods should have been exported. Actually that is true i can see the exported function using dumpbin but they have very strange name like ?Setup@CTG_ACQ@@QAEK.

I know this is the name made by the compiler where setup is my function and CTG_ACQ is the class declared as __declspec(dllexport).

How is possible to change that name?
Should i add a .def file? but this should be in conflict with the __declspec(dllexport) directive.

any help will be appreciated

thanks

Davide

ok solved,


if i use a class the name exported are strange, if i use extern "C" and the functions outside the class it is ok.
i wonder why, anyway

bye

C++ mangled names help to detect incorrect declarations in separately compiled modules on linkage stage. These strange names (for linker and debugger, not a human reading contain not only names as such but signatures (function parameter types, for example). Correctly declared C++ names yield identical mangled names.
In extern "C" case this useful guard is not active.
