我知道externC应该暗示没有名字装饰，但它从来都不是以前的情况。

是的，这是预期的。

如果你阅读了MSDN文档，对于externC，你可以阅读它。并且，你会发现它将明确地创建无瑕疵的名字。

extern" ; C"我总是这样做，所以如果它不适合你，那可能是另一个问题。

externC我总是这样做，所以如果它不适合你，那可能还有另外一个问题。

你能帮我调试吗请：


C：\work\dll> cat dll.cpp

extern" C" __declspec（dllexport）int __stdcall fndll（void）;


//这是导出函数的一个示例。

externC __declspec（dllexport）int __stdcall fndll（void）

{

返回42;

According to dumpbin, my extern "C" __stdcall''ed functions are not
decorated... According to depends they are not decorated... According to the
documentation, (and previous releases of vc++), they should be...

Is this expected?

I know extern "C" should imply no name decorating but its never been the
case before.

Thanks

Yes, this is to be expected.
If you read the MSDN docs, for extern "C" and, you''ll find that it will
explicitly create unmangled names.

extern "C" has always done this for me, so if it didn''t for you, there was
probably another problem.

Can you help me debug this then please:

C:\work\dll>cat dll.cpp
extern "C" __declspec(dllexport) int __stdcall fndll(void);

// This is an example of an exported function.
extern "C" __declspec(dllexport) int __stdcall fndll(void)
{
return 42;
