I'm looking for a w开发者_如何学运维ay (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?If you're content with other tools then there are a number that do list exported functions. One is Microsoft's dumpbin
, use the /exports
option.
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;
}
