DLL function names using dumpbin.exe
提问by TomiL
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:
我在 Visual Studio 2010 中编写了一个包含大量函数和类的 .dll 库。当我查看文件内容时：
dumpbin.exe /EXPORTS myDll.dll
I get long function names with some kind of a function location pointer, which looks like this (second entry in .dll):
我得到了带有某种函数位置指针的长函数名称，如下所示（.dll 中的第二个条目）：
2 1 0001100A ?Initialize@codec@codecX@@SANNN@Z = @ILT+5(?Initialize@codec@codecX@@SANNN@Z)
This is somehow hard to read, but I saw "nicer" procedure/function list from other .dll-s, like this:
这有点难以阅读，但我从其他 .dll-s 中看到了“更好”的过程/函数列表，如下所示：
141 8C 00002A08 PogoDbWriteValueProbeInfo
How can I make that .dll list look that way?
我怎样才能让 .dll 列表看起来像那样？
P.S.: my dll source code looks like this:
PS：我的dll源代码是这样的：
namespace codecX
{
class codec
{
public:
static __declspec(dllexport) double Initialize(double a, double b);
...

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:
您需要将这些静态成员函数拉入全局地址空间，然后用 extern "C" 包装它们。这将抑制 C++ 名称修改，而是为您提供不那么难看的 C 名称修改：
extern "C" __declspec(dllexport) Initialize(double a, double b)
{
codec::Initialize(a, b);
}
and then remove the __declspec(dllexport) on your static member functions:
然后删除静态成员函数上的 __declspec(dllexport)：
class codec
{
public:
static double Initialize(double a, double b);
}

This is called name-manglingand happens when you compile C++ with a C++-compiler.
In order to retain the "humand-readable" names you'll have to use extern "C"when declaring and defining your classes and your functions. i.e.
这称为名称修改，当您使用 C++ 编译器编译 C++ 时会发生这种情况。为了保留extern "C"在声明和定义类和函数时必须使用的“人类可读”名称。IE
extern "C" void myFunction(int, int);
