怎么卸载远程DLL
一些进程管理软件都有枚举某个进程用到的DLL，并且可以卸载其中某个DLL。
我的程序也想实现这么一个功能。
除了远程注入的方法（CreateRemoteThread）之外，还有什么办法可以卸载远程进程中的某个DLL？

C/C++ code

BOOL WINAPI FreeDllW(DWORD dwPid, LPCWSTR lpName){    BOOL bRet = FALSE;    size_t dwSize = 0;    DWORD dwWritten = 0;    DWORD dwHandle = 0;    LPVOID lpBuf = NULL;    HANDLE hProcess = OpenProcess(PROCESS_CREATE_THREAD |                                  PROCESS_VM_OPERATION |                                  PROCESS_VM_WRITE,                                  FALSE,                                  dwPid);    if (hProcess == NULL)    {        return FALSE;    }    dwSize = (_tcslen(lpName) + 1) * 2;    lpBuf = VirtualAllocEx(hProcess, NULL, dwSize, MEM_COMMIT, PAGE_READWRITE);    if (!WriteProcessMemory(hProcess, lpBuf, (LPVOID)lpName, dwSize, &dwWritten))    {        goto Cleanup;    }    LPVOID pFun = GetProcAddress(GetModuleHandle(TEXT("Kernel32")), "GetModuleHandleW");    HANDLE hThread = CreateRemoteThread(hProcess,                                        NULL,                                        0,                                        (LPTHREAD_START_ROUTINE)pFun,                                        lpBuf,                                        0,                                        NULL);    if (hThread == NULL)    {        goto Cleanup;    }    WaitForSingleObject(hThread, INFINITE);    GetExitCodeThread(hThread, &dwHandle);    CloseHandle(hThread);    pFun = GetProcAddress(GetModuleHandle(TEXT("Kernel32")), "FreeLibraryAndExitThread");    hThread = CreateRemoteThread(hProcess,                                 NULL,                                 0,                                 (LPTHREAD_START_ROUTINE)pFun,                                 (LPVOID)dwHandle,                                 0,                                 NULL);    WaitForSingleObject(hThread, INFINITE);    CloseHandle(hThread);    bRet = TRUE;Cleanup:    if (lpBuf != NULL)    {        VirtualFreeEx(hProcess, lpBuf, dwSize, MEM_DECOMMIT);        lpBuf = NULL;    }    CloseHandle(hProcess);    return bRet;}
