C ++：找出装饰名字 [英] C++ : Finding out decorated names

问题描述

如何找到将被分配给每个方法名称的装饰名称？我试图找出装饰的名字，以便我可以在DLL中导出它。

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 .

推荐答案

。 DEF文件正在使用

忘记.DEF文件。他们是过去的事情。

.DEF file are still being used?

Forget .DEF files. They are a thing of the past.

通过__declspec（dllimport / dllexport）导出您的函数，即C函数或C ++符号。

Export your functions, be them C functions or C++ symbols, through __declspec(dllimport/dllexport).

如果您真的需要未装饰的名称，请使用Greg Hewgill，__declspec（dllimport / dllexport）关键字的建议，结合externC，将剥离其装饰符号...

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...

有一些有效的原因：你想导出将被C代码使用的代码，或者您想使用不同编译器编译的模块使用DLL。

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.

而第二个原因，我会产生一个DLL，每个编译器，并保持装饰。

And for the second reason, I would instead produce one DLL per compiler, and keep the decorations.

除了这些原因，为什么要删除装饰？

Aside those reasons, why do you want the decorations removed?

恰恰相反。

如果你正在使用一个编译器（我认为你这样做，因为你想使用装饰的名字，而不是externC的那些），然后保持C ++的装饰/名称变得简单。

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.

这样，你可以使用完整的C ++电源，即命名空间，类，函数/方法重载等。

In this way, you'll be able to use full C++ power, that is, namespaces, classes, function/method overloads, etc..

仍然是用符号装饰手动玩是一个食谱灾难：使用dllexport导出您的符号，而无需处理另一个（.DEF）文件。

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.
