C++获取当前进程IAT的方法

#include <windows.h>
#include <stdio.h>

int main(int argc, char* argv[])
{
HMODULE hModule = ::GetModuleHandleA(NULL);
IMAGE_DOS_HEADER* pDosHeader = (IMAGE_DOS_HEADER*)hModule;
IMAGE_OPTIONAL_HEADER* pOpNtHeader = (IMAGE_OPTIONAL_HEADER*)((BYTE*)hModule + pDosHeader->e_lfanew + 24); //这里加24
IMAGE_IMPORT_DESCRIPTOR* pImportDesc = (IMAGE_IMPORT_DESCRIPTOR*)((BYTE*)hModule + pOpNtHeader->DataDirectory[IMAGE_DIRECTORY_ENTRY_IMPORT].VirtualAddress);

while (pImportDesc->FirstThunk)
{
char* pszDllName = (char*)((BYTE*)hModule + pImportDesc->Name);
printf("模块名称:%s\\n", pszDllName);

DWORD n = 0;
//一个IMAGE_THUNK_DATA就是一个导入函数
IMAGE_THUNK_DATA* pThunk = (IMAGE_THUNK_DATA*)((BYTE*)hModule + pImportDesc->OriginalFirstThunk);
while (pThunk->u1.Function)
{
//取得函数名称
char* pszFuncName = (char*)((BYTE*)hModule+pThunk->u1.AddressOfData+2); //函数名前面有两个..
printf("function name:%-25s, ", pszFuncName);
//取得函数地址
PDWORD lpAddr = (DWORD*)((BYTE*)hModule + pImportDesc->FirstThunk) + n; //从第一个函数的地址，以后每次+4字节
printf("addrss:%X\\n", lpAddr);
n++; //每次增加一个DWORD
pThunk++;
}
printf("\\n");
pImportDesc++;
}
return 0;
}
