我尝试使用以下代码列出 PE 文件的导入 DLL,但它不起作用,并且 windows 说我运行它时 exe 已停止工作。在代码中,我只是使用 CreateFileMapping 函数将给定的 exe 文件映射到内存中,然后使用 Win32 API 中给出的适当结构来浏览每个部分。我该如何纠正?
#include <stdio.h>
#include <windows.h>
//add Pointer Values
#define MakePtr( cast, ptr, addValue ) (cast)( (unsigned long)(ptr)+(unsigned long)(addValue))
int main(int argc , char ** argv) //main method
{
HANDLE hMapObject, hFile;//File Mapping Object
LPVOID lpBase;//Pointer to the base memory of mapped
PIMAGE_DOS_HEADER dosHeader;//Pointer to DOS Header
PIMAGE_NT_HEADERS ntHeader;//Pointer to NT Header
PIMAGE_IMPORT_DESCRIPTOR importDesc;//Pointer to import descriptor
hFile = CreateFile(argv[1],GENERIC_READ,FILE_SHARE_READ,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);//Open the Exe File
if(hFile == INVALID_HANDLE_VALUE){
printf("\nERROR : Could not open the file specified\n");
}
hMapObject = CreateFileMapping(hFile,NULL,PAGE_READONLY,0,0,NULL);
lpBase = MapViewOfFile(hMapObject,FILE_MAP_READ,0,0,0);//Mapping Given EXE file to Memory
dosHeader = (PIMAGE_DOS_HEADER)lpBase;//Get the DOS Header Base
//verify dos header
if ( dosHeader->e_magic == IMAGE_DOS_SIGNATURE)
{
ntHeader = MakePtr(PIMAGE_NT_HEADERS, dosHeader, dosHeader->e_lfanew);//Get the NT Header
//verify NT header
if (ntHeader->Signature == IMAGE_NT_SIGNATURE ){
importDesc = MakePtr(PIMAGE_IMPORT_DESCRIPTOR, dosHeader,ntHeader->OptionalHeader.DataDirectory[IMAGE_DIRECTORY_ENTRY_IMPORT].VirtualAddress);
while (importDesc->Name)
{
printf("%s\n",MakePtr(char*, dosHeader,importDesc->Name));
importDesc++;
}
}
}
getchar();
}
