使用 def 文件和 extern "C" 进行名称修改

我正在创建一个基本的 COM 组件，以便我可以练习创建它们。

我正在使用 PRIVATE 关键字从 .def 文件导出 DllRegisterServer、DllUnregisterServer、DllGetClassObject 和 DllCanUnloadNow（我认为 Microsoft 需要它）。

不管怎样，我用 extern "C" 指定了所有 4 个函数，但我仍然受到损坏。这是我的 .def：

EXPORTS
DllRegisterServer PRIVATE
DllUnregisterServer PRIVATE
DllGetClassObject PRIVATE
DllCanUnloadNow PRIVATE

这是来自 dumpbin /EXPORTS 的重整

_DllCanUnloadNow@0
_DllGetClassObject@12
_DllRegisterServer@0
_DllUnregisterServer@0

我知道 extern "C" 有帮助，因为没有它我会得到非常糟糕的重整，但我认为带有 extern "C" 的 .def 应该摆脱名称损坏？

我的编译器是VC++ Express 2008。链接器命令行:

/OUT:"G:\Programming\COM\BasicMathCOM\BasicMath\Release\BasicMath.dll" /INCRMENTAL:NO /NOLOGO /DLL /MANIFEST /MANIFESTFILE:"Release\BasicMath.dll.intermediate.manifest" / MANIFESTUAC:"level='asInvoker' uiAccess='false'" /DEBUG /PDB:"g:\Programming\COM\BasicMathCOM\BasicMath\Release\BasicMath.pdb" /SUBSYSTEM:WINDOWS /OPT:REF /OPT:ICF / LTCG /DYNAMICBASE /NXCOMPAT /MACHINE:X86 /ERRORREPORT:PROMPT kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib

+ /DEF:BasicMath.def，我在附加选项下添加了它。

I'm creating a basic COM component so I can practice creating them.

I'm exporting DllRegisterServer, DllUnregisterServer,DllGetClassObject and DllCanUnloadNow from a .def file with the PRIVATE keyword(I think Microsoft requires it).

Anway, I specified all 4 functions with extern "C" and yet I'm still getting mangling.
Here is my .def:

EXPORTS
DllRegisterServer PRIVATE
DllUnregisterServer PRIVATE
DllGetClassObject PRIVATE
DllCanUnloadNow PRIVATE

Here is the mangling from dumpbin /EXPORTS

_DllCanUnloadNow@0
_DllGetClassObject@12
_DllRegisterServer@0
_DllUnregisterServer@0

I know the extern "C" helps, because I get really bad mangling without it, but I thought the .def with extern "C" was supposed to get rid of name mangling?

My compiler is VC++ Express 2008.

+/DEF:BasicMath.def, which I had added under additional options.
