列出 DLL 的导出函数-C/C++问题

Listing the exported functions of a DLL(列出 DLL 的导出函数)

本文介绍了列出 DLL 的导出函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在寻找一种方法(在 C++/Windows 中)使用 dbgHelp 列出 DLL 的导出函数(甚至可能是未导出的方法).
有人知道哪种方法可以做到吗?

I'm looking for a way (in C++/Windows) to list the exported functions of a DLL (and maybe even methods which are not exported) using dbgHelp.
Does anybody know which method can do it?

推荐答案

有代码此处执行此操作.我已经清理了一下，它在下面显示的场景中工作，从 Kernel32.Dll 检索函数名称.

There is code here to do this. I have cleaned it up a bit and it worked in the scenario shown below, retrieving function names from Kernel32.Dll.

#include "imagehlp.h"

void ListDLLFunctions(string sADllName, vector<string>& slListOfDllFunctions)
{
    DWORD *dNameRVAs(0);
    _IMAGE_EXPORT_DIRECTORY *ImageExportDirectory;
    unsigned long cDirSize;
    _LOADED_IMAGE LoadedImage;
    string sName;
    slListOfDllFunctions.clear();
    if (MapAndLoad(sADllName.c_str(), NULL, &LoadedImage, TRUE, TRUE))
    {
        ImageExportDirectory = (_IMAGE_EXPORT_DIRECTORY*)
            ImageDirectoryEntryToData(LoadedImage.MappedAddress,
            false, IMAGE_DIRECTORY_ENTRY_EXPORT, &cDirSize);
        if (ImageExportDirectory != NULL)
        {
            dNameRVAs = (DWORD *)ImageRvaToVa(LoadedImage.FileHeader, 
                LoadedImage.MappedAddress,
            ImageExportDirectory->AddressOfNames, NULL);
            for(size_t i = 0; i < ImageExportDirectory->NumberOfNames; i++)
            {
                sName = (char *)ImageRvaToVa(LoadedImage.FileHeader, 
                        LoadedImage.MappedAddress,
                       dNameRVAs[i], NULL);
             slListOfDllFunctions.push_back(sName);
            }
        }
        UnMapAndLoad(&LoadedImage);
    }
}

int main(int argc, char* argv[])
{
    vector<string> names;
    ListDLLFunctions("KERNEL32.DLL", names);

    return 0;   
}
