Функция SendARP (iphlpapi.h)

Функция SendARP отправляет запрос протокола ARP для получения физического адреса, соответствующего указанному целевому IPv4-адресу.

Синтаксис

Параметры

Целевой IPv4-адрес в виде структуры IPAddr . Запрос ARP пытается получить физический адрес, соответствующий этому IPv4-адресу.

Исходный IPv4-адрес отправителя в виде структуры IPAddr . Этот параметр является необязательным и используется для выбора интерфейса для отправки запроса на запись ARP. Вызывающий объект может указать ноль, соответствующий INADDR_ANY IPv4-адресу для этого параметра.

Указатель на массив переменных ULONG . Этот массив должен содержать по крайней мере два элемента ULONG для хранения физического адреса Ethernet или кольца маркеров. Первые шесть байтов этого массива получают физический адрес, соответствующий IPv4-адресу, указанному параметром DestIP .

[in, out] PhyAddrLen

При входе указатель на значение ULONG , указывающее максимальный размер буфера в байтах, приложение отложило на получение физического адреса или MAC-адреса. Размер буфера должен быть не менее 6 байт для физического адреса Ethernet или кольца маркеров.

Буфер для получения физического адреса указывает на параметр pMacAddr .

При успешном выходе этот параметр указывает на значение, указывающее количество байтов, записанных в буфер, на который указывает pMacAddr.

Возвращаемое значение

Если функция завершается успешно, возвращаемое значение NO_ERROR.

Если функция завершается ошибкой, возвращаемое значение является одним из следующих кодов ошибок.

Код возврата	Описание
ERROR_BAD_NET_NAME	Не найдено сетевое имя». Эта ошибка возвращается в Windows Vista и более поздних версиях, когда ответ ARP на запрос SendARP не получен. Эта ошибка возникает, если не удалось достичь адреса IPv4 назначения, так как он находится не в той же подсети или на конечном компьютере не работает.
ERROR_BUFFER_OVERFLOW	Имя файла слишком длинное. Эта ошибка возвращается в Windows Vista, если значение ULONG , указываемое параметром PhyAddrLen , меньше 6, то размер, необходимый для хранения полного физического адреса.
ERROR_GEN_FAILURE	Устройство, подключенное к системе, не работает. Эта ошибка возвращается в Windows Server 2003 и более ранних версиях, когда ответ ARP на запрос SendARP не был получен. Эта ошибка может возникнуть, если не удалось связаться с адресом IPv4 назначения, так как он находится не в той же подсети или на конечном компьютере не работает.
ERROR_INVALID_PARAMETER	Один из параметров недопустим. Эта ошибка возвращается в Windows Server 2003 и более ранних версиях, если параметр pMacAddr или PhyAddrLen является указателем NULL .
ERROR_INVALID_USER_BUFFER	Предоставленный пользовательский буфер недопустим для запрошенной операции. Эта ошибка возвращается в Windows Server 2003 и более ранних версиях, если значение ULONG , на которое указывает параметр PhyAddrLen , равно нулю.
ERROR_NOT_FOUND	Элемент не найден. Эта ошибка возвращается в Windows Vista, если параметр SrcIp не указывает исходный IPv4-адрес на интерфейсе на локальном компьютере или IP-адрес INADDR_ANY (IPv4-адрес 0.0.0.0.0).
ERROR_NOT_SUPPORTED	Функция SendARP не поддерживается операционной системой, работающей на локальном компьютере.
Другое	Если функция завершается ошибкой, используйте FormatMessage , чтобы получить строку сообщения для возвращенной ошибки.

Комментарии

Функция SendARP используется для запроса физического аппаратного адреса (иногда называемого MAC-адресом), который соответствует указанному IPv4-адресу назначения. Если запрошенная информация отсутствует в таблице ARP на локальном компьютере, функция SendARP вызовет отправку запроса ARP для получения физического адреса. Если функция выполнена успешно, физический адрес, соответствующий указанному целевому IPv4-адресу, возвращается в массиве, на который указывает параметр pMacAddr .

Физический адрес IPv4-адреса доступен только в том случае, если целевой IPv4-адрес находится в локальной подсети (IPv4-адрес можно получить напрямую без прохождения маршрутизаторов). Функция SendARP завершится ошибкой, если целевой IPv4-адрес не находится в локальной подсети.

Если функция SendARP успешно работает в Windows Vista и более поздних версиях, таблица ARP на локальном компьютере обновляется с результатами. Если функция SendARP успешно работает в Windows Server 2003 и более ранних версиях, таблица ARP на локальном компьютере не затрагивается.

Функция SendARP в Windows Vista и более поздних версиях возвращает разные возвращаемые значения ошибок, отличные от функции SendARP в Windows Server 2003 и более ранних версиях.

В Windows Vista и более поздних версиях указатель NULL , переданный в качестве параметра pMacAddr или PhyAddrLen в функцию SendARP , приводит к нарушению доступа, и приложение завершается. Если ошибка возникает в Windows Vista и более поздних версиях, а ERROR_BAD_NET_NAME, ERROR_BUFFER_OVERFLOW или ERROR_NOT_FOUND возвращается, значение ULONG , указываемое параметром PhyAddrLen , равно нулю. Если значение ULONG , указываемое параметром PhyAddrLen , меньше 6 в Windows Vista и более поздних версиях, функция SendARP возвращает ERROR_BUFFER_OVERFLOW указывая, что буфер для получения физического адреса слишком мал. Если параметр SrcIp указывает IPv4-адрес, который не является интерфейсом на локальном компьютере, функция SendARP в Windows Vista и более поздних версий возвращает ERROR_NOT_FOUND.

В Windows Server 2003 и более ранних версиях указатель NULL, переданный в качестве параметра pMacAddr или PhyAddrLen в функцию SendARP, возвращает ERROR_INVALID_PARAMETER. Если ошибка возникает в Windows Server 2003 и более ранних версиях и возвращается ERROR_GEN_FAILURE или ERROR_INVALID_USER_BUFFER , значение ULONG , указываемое параметром PhyAddrLen , равное нулю. Если значение ULONG , на которое указывает параметр PhyAddrLen , меньше 6 в Windows Server 2003 и более ранних версиях, функция SendARP не возвращает ошибку, но возвращает только часть аппаратного адреса в массиве, на который указывает параметр pMacAddr . Таким образом, если значение, на которое указывает параметр PhyAddrLen , равно 4, то в массиве, на который указывает параметр pMacAddr , возвращаются только первые 4 байта аппаратного адреса. Если параметр SrcIp указывает IPv4-адрес, который не является интерфейсом на локальном компьютере, функция SendARP в Windows Server 2003 и более ранних версиях игнорирует параметр SrcIp и использует IPv4-адрес на локальном компьютере для исходного IPv4-адреса.

Функция GetIpNetTable извлекает таблицу ARP на локальном компьютере, который сопоставляет IPv4-адреса с физическими адресами.

Функция CreateIpNetEntry создает запись ARP в таблице ARP на локальном компьютере.

Функция DeleteIpNetEntry удаляет запись ARP из таблицы ARP на локальном компьютере.

Функция SetIpNetEntry изменяет существующую запись ARP в таблице ARP на локальном компьютере.

Функция FlushIpNetTable удаляет все записи ARP для указанного интерфейса из таблицы ARP на локальном компьютере.

В Windows Vista и более поздних версиях функция ResolveIpNetEntry2 может использоваться для замены функции SendARP . Запрос ARP отправляется, если элемент адресаMIB_IPNET_ROW2 структуры , переданной функции ResolveIpNetEntry2 , является IPv4-адресом.

В Windows Vista новую группу функций можно использовать для доступа, изменения и удаления записей таблицы ARP, когда элемент адреса структуры MIB_IPNET_ROW2 , передаваемой этим функциям, является IPv4-адресом. Новые функции включают следующие функции: GetIpNetTable2, CreateIpNetEntry2, DeleteIpNetEntry2, FlushIpNetTable2 и SetIpNetEntry2.

Сведения о типе данных IPAddr см. в разделе «Типы данных Windows». Чтобы преобразовать IP-адрес между точечной десятичной нотацией и форматом IPAddr , используйте функции inet_addr и inet_ntoa .

Примеры

В следующем коде показано, как получить аппаратный или MAC-адрес, связанный с указанным IPv4-адресом.

I am creating a program to populate a disk with a dummy file system.

Currently, I am writing files of variable sizes using WriteFile.

        WriteFile(hFile, FileData, i * 1024, &dwWrote, NULL);
        err = GetLastError();

err returns #1784 which translates to

The supplied user buffer is not valid for the requested operation. ERROR_INVALID_USER_BUFFER

So for the first 24 files, the write operation works. For file #25 on, the write operation fails.
The files are still created but the WriteFile function does not populate the files.

Any ideas on how to get past ERROR_INVALID_USER_BUFFER?

Every reference I can find to the error is limited to crashing programs and I cannot figure out how it relates to the issue I am experiencing.

EDIT:

FileData = (char *) malloc(sizeof(char) * (size_t)k * 1024);
memset(FileData, 245, sizeof(char) * (size_t)k * 1024);

FileData is set and allocated to the size of the maximum anticipate buffer.
i is the loop variable that iterates until it increments to the Maximum Size (k).

Hello,

 I’m trying to get informations about an USB device inserted into my system.
My application works in C++ and I’m porting it to c#.

Everytime, the call to SetupDiOpenDeviceInterface fails with ERROR_INVALID_USER_BUFFER.
The doc says that it does not matter when info is filled. But this is not my case.
I’m now running out of ideas please help.

I first call RegisterDeviceNotification to get notified when an USB device is inserted.
       public bool DoRegisterDeviceInterface(IntPtr mHandle,Guid InterfaceClassGuid)
        {
            DEV_BROADCAST_DEVICEINTERFACE NotificationFilter = new DEV_BROADCAST_DEVICEINTERFACE();
            NotificationFilter.dbcc_size = Marshal.SizeOf(NotificationFilter);
            NotificationFilter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE;
            NotificationFilter.dbcc_classguid = InterfaceClassGuid;

            IntPtr buffer = Marshal.AllocHGlobal(NotificationFilter.dbcc_size);
            Marshal.StructureToPtr(NotificationFilter, buffer, true);

                        mDeviceNotifyHandle = RegisterDeviceNotification(mHandle, buffer, DEVICE_NOTIFY_WINDOW_HANDLE | DEVICE_NOTIFY_ALL_INTERFACE_CLASSES);
            return true;
        }

I’m correctly notified when it fires:
      protected override void WndProc(ref Message m)
        {
            switch (m.Msg)
            {
                case WM_DEVICECHANGE:
                    // The WParam value identifies what is occurring.
                    // n = (int)m.WParam;
                    switch (m.WParam.ToInt32())
                    {
                        case DBT_DEVICEARRIVAL:
                        case DBT_DEVICEREMOVECOMPLETE:
                            DEV_BROADCAST_DEVICEINTERFACE dvi = (DEV_BROADCAST_DEVICEINTERFACE)m.GetLParam(typeof(DEV_BROADCAST_DEVICEINTERFACE));
                            DoGetDeviceDetails(dvi);
                            break;
                    }
                    break;

Я создаю программу для заполнения диска фиктивной файловой системой.

В настоящее время я пишу файлы с переменными размерами с помощью WriteFile.

        WriteFile(hFile, FileData, i * 1024, &dwWrote, NULL);
        err = GetLastError();

err возвращает # 1784, что означает

Загруженный буфер пользователя недействителен для запрошенной операции. ERROR_INVALID_USER_BUFFER

Итак, для первых 24 файлов работает операция записи. Для файла № 25 операция записи не выполняется.
Файлы все еще созданы, но функция WriteFile не заполняет файлы.

Любые идеи о том, как пройти мимо ERROR_INVALID_USER_BUFFER?

Каждая ссылка, которую я могу найти, связана с ошибкой программ, и я не могу понять, как она связана с проблемой, которую я испытываю.

EDIT:

FileData = (char *) malloc(sizeof(char) * (size_t)k * 1024);
memset(FileData, 245, sizeof(char) * (size_t)k * 1024);

FileData устанавливается и назначается размеру максимального ожидаемого буфера.
i — это переменная цикла, которая выполняет итерацию до тех пор, пока она не увеличится до максимального размера (k).

I’d be happy to help in any way I can. I’m hoping to use this for my master’s research, so I’m definitely interested in getting this working.

I updated to your latest version of libusb and I’m having a different problem now. I now get libusb: error [windows_transfer_callback] detected I/O error 87: [87] The parameter is incorrect. and the program crashes at the following (in my own program):

I had to disable the libusb_detach_kernel_driver portion of ps4eye.cpp (link), otherwise I get «not supported» errors. Apparently the detach code isn’t supported in Windows. Additionally, I had to disable this line after enabling debug messages since ctrl.bInterfaceNumber isn’t initialized.

I tried doing all this on a fresh computer to check about the interfaces. USB_BOOT shows fine, and when uploading the firmware, Windows reconnects to the camera and automatically installs a system driver:

At this point, only Interface 0 was visible, same as your situation. I tried running the SDL test tool and it tells me that the device can’t be opened, which I gather is fine since I’m supposed to replace the composite parent with libusbK.

After replacing the composite parent with libusbK, I get the [windows_transfer_callback] error above when using the SDL test tool, but only when running in Release configuration. In Debug, the program will run without complaining, but the screen is black.

Let me know if there’s any other way I can help!
