Question

您好我试图在Windows中使用c / c ++构建外部调试器。到目前为止，我现在的目标是将调试器附加到进程，然后捕获一些断点。到目前为止，我设法使用CreateProcessA从代码运行进程，并成功捕获断点。但我想附加到外部流程。这是我的代码：

void attachProcess(DWORD pid) {
    errCheck("before obtaining handle");
    /*
     * if I uncomment those 2 lines I also succeed to obtain the handle but the pid changes(it finds the proper process, tested it)
     *
    HWND wnd = FindWindowA(NULL, "Kalkulator");
    GetWindowThreadProcessId(wnd, &pid);
     */
    HANDLE handle = OpenProcess(PROCESS_ALL_ACCESS, 0, pid);
    if(handle == 0) {
        log("no process hanle obtained - process not found", ERR);
        return;
    }
    log("handler obtained", POSITIVE);
    log<void*>(handle, POSITIVE);
    errCheck("after obtaining handle");
    if(DebugActiveProcess(pid)) {
        log("attached to process, pid:",POSITIVE);
        log<DWORD>(pid,POSITIVE);
        DEBUG_EVENT debug_event = {0};
        while(WaitForDebugEvent(&debug_event, INFINITE)) {
            handleDebugEvent(&debug_event);
            ContinueDebugEvent(debug_event.dwProcessId, debug_event.dwThreadId, DBG_CONTINUE);
        }
    } else {
        log("unable to attach to process, pid:", ERR);
        log<DWORD>(pid,ERR);
        errCheck("attaching");
    }
    CloseHandle(&handle);
}

此代码成功获取句柄，但它在DebugActiveProcess上崩溃，但错误为50 ERROR_NOT_SUPPORTED。我的Windows是64位，所以是计算过程（我假设因为在任务管理器中没有注意它是32位）。有什么想法我做错了什么？谢谢！

这是示例输出btw：

[+] handler obtained
[+] 0xe8
[!] unable to attach to process, pid:
[!] 7212
[!] attaching | error occured 
[!] 50
