DLL函数名称使用dumpbin.exe [英] DLL function names using dumpbin.exe

问题描述

我在visual studio 2010中编写了一个具有很多功能和类的.dll库。
当我查看文件的内容时：

I have written a .dll library with lots of functions and classes in visual studio 2010. When I look at the content of the file with:

dumpbin.exe /EXPORTS myDll.dll

函数名称具有某种函数位置指针，看起来像这样（.dll中的第二个条目）：

I get long function names with some kind of a function location pointer, which looks like this (second entry in .dll):

          2    1 0001100A ?Initialize@codec@codecX@@SANNN@Z = @ILT+5(?Initialize@codec@codecX@@SANNN@Z)

这是一个很难看的，但是我看到其他.dll-s的更好的程序/功能列表，如下所示：

This is somehow hard to read, but I saw "nicer" procedure/function list from other .dll-s, like this:

141   8C 00002A08 PogoDbWriteValueProbeInfo

.dll列表看起来像这样？

PS：我的dll源代码如下所示：

namespace codecX
{
   class codec
   {
      public:
      static __declspec(dllexport) double Initialize(double a, double b);
      ...

推荐答案

你需要拉那些静态成员函数进入全局地址空间，然后用
externC包装它们。这将抑制C ++名称的变化，而不是给你C名称变得不那么丑陋：

You need to pull those static member functions into the global address space and then wrap them with extern "C". This will suppress the C++ name mangling and instead give you C name mangling which is less ugly:

extern "C" __declspec(dllexport) Initialize(double a, double b)
{
    codec::Initialize(a, b);
}

然后删除静态成员函数上的__declspec（dllexport） p>

and then remove the __declspec(dllexport) on your static member functions:

class codec
{
    public:
        static double Initialize(double a, double b);
}
