Wie bekomme ich die Seriennummer des Laufwerks in C/C++?

Dies wurde bereits beantwortet aber es ist eine C # -Lösung. Wie mache ich das in C oder C++?

Dafür gibt es mehrere Möglichkeiten. Sie können mithilfe des Systems Anrufe tätigen, um die Informationen abzurufen. 

Für Linux:

system("hdparm -i /dev/hda | grep -i serial");

Ohne Verwendung des Systems:

static struct hd_driveid hd;
int fd;

if ((fd = open("/dev/hda", O_RDONLY | O_NONBLOCK)) < 0) {
    printf("ERROR opening /dev/hda\n");
    exit(1);
}

if (!ioctl(fd, HDIO_GET_IDENTITY, &hd)) {
    printf("%.20s\n", hd.serial_no);
} else if (errno == -ENOMSG) {
    printf("No serial number available\n");
} else {
    perror("ERROR: HDIO_GET_IDENTITY");
    exit(1);
}

Für Windows:

system("wmic path win32_physicalmedia get SerialNumber");

Ohne System (Basierend auf Abrufen von WMI-Daten ):

hres = pSvc->ExecQuery(
    bstr_t("WQL"),
    bstr_t("SELECT SerialNumber FROM Win32_PhysicalMedia"),
    WBEM_FLAG_FORWARD_ONLY | WBEM_FLAG_RETURN_IMMEDIATELY, 
    NULL,
    &pEnumerator);
hr = pclsObj->Get(L"SerialNumber", 0, &vtProp, 0, 0);

Hier ist eine complete -Lösung für Windows , die WMI-Aufrufe ohne mit cmd oder system umgibt.
So können Sie problemlos alles von WMI erhalten, einschließlich der Seriennummer der Festplatte. 

Alles was Sie tun müssen, ist anzurufen:

getWmiQueryResult(L"SELECT SerialNumber FROM Win32_PhysicalMedia", L"SerialNumber");

PS. Es basiert auf offizielle Dokumentation und verbessert außerdem die Fehlerbehandlung und -bereinigung. Sie können auch this oder this zum Erstellen von WQL-Abfragen verwenden.

Für Linux ohne root/Sudo-Zugriff:

Installieren Sie libudev-dev. Verwenden Sie den folgenden Code:

#include <stdio.h>
#include <string.h>
#include <libudev.h>
#include <sys/stat.h>


int main()
{
    struct udev            *ud      = NULL;
    struct stat             statbuf;
    struct udev_device     *device  = NULL;
    struct udev_list_entry *entry   = NULL;

    ud = udev_new();
    if (NULL == ud) {
        fprintf(stderr, "Failed to create udev.\n");
    } else {
        if (0 != stat("/dev/sda", &statbuf)) {

        } else {
            device = udev_device_new_from_devnum(ud, 'b', statbuf.st_rdev);
            if (NULL == device) {
                fprintf(stderr, "Failed to open /dev/sda.\n");
            } else {
                entry = udev_device_get_properties_list_entry(device);
                while (NULL != entry) {
                    if (0 == strcmp(udev_list_entry_get_name(entry),
                                    "ID_SERIAL")) {
                        break;
                    }

                    entry = udev_list_entry_get_next(entry);
                }

                printf("Serial ID: %s\n", udev_list_entry_get_value(entry));

                udev_device_unref(device);
            }
        }

        (void)udev_unref(ud);
    }

    return 0;
} 

Der Code basiert teilweise auf der libudev-Dokumentation und teilweise auf dem Quellcode für udevadm.

Für Windows: wmic path win32_physicalmedia get SerialNumber

Hier ein Beispiel, wie Sie die Daten als string erhalten, wenn Sie einen Befehl ausführen. Wir verwenden _popen anstelle der oben vorgeschlagenen system

#include <cstdio>
#include <iostream>
#include <memory>
#include <stdexcept>
#include <string>
#include <array>

exec("wmic path win32_physicalmedia get SerialNumber");

std::string exec(const char* cmd) {
    std::array<char, 128> buffer;
    std::string result;
    std::shared_ptr<FILE> pipe(_popen(cmd, "r"), _pclose);
    if (!pipe) throw std::runtime_error("_popen() failed!");
    while (!feof(pipe.get())) {
        if (fgets(buffer.data(), 128, pipe.get()) != NULL)
            result += buffer.data();
    }
    return result;
}

Auf meinem System gibt es vier vom Benutzer lesbare Dateien, die Hex-Dumps der Geräteinformationen enthalten. Zwei davon sind Nullen, zwei andere enthalten Informationen über Datenträger und DVD. DVD hat keine Seriennummer und die Seriennummer der Festplatte beginnt mit dem Offset 0x20.
