Cela a déjà été répondu mais c'est une solution C #. Comment est-ce que je fais ceci en C ou C++?
Il y a quelques façons de le faire. Vous pouvez faire des appels en utilisant le système pour obtenir les informations.
system("hdparm -i /dev/hda | grep -i serial");
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);
}
system("wmic path win32_physicalmedia get SerialNumber");
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);
Voici un complet solution pour Windows qui englobe les appels WMI sans en utilisant cmd ou system.
Ainsi, vous pouvez facilement obtenir quelque chose de WMI, y compris le numéro de série du disque dur.
Tout ce que vous avez à faire est d'appeler:
getWmiQueryResult(L"SELECT SerialNumber FROM Win32_PhysicalMedia", L"SerialNumber");
PS Il est basé sur la documentation officielle et effectue en outre une meilleure gestion des erreurs et un meilleur nettoyage. Vous pouvez également utiliser this ou this pour créer des requêtes WQL.

Installez libudev-dev. Utilisez un code similaire à celui ci-dessous:
#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)) {
fprintf(stderr, "Failed to stat /dev/sda.\n");
} 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;
}
Le code est basé en partie sur la documentation de libudev et en partie sur le code source de udevadm.
Pour Windows: wmic path win32_physicalmedia get SerialNumber
Voici un exemple comment récupérer les données sous la forme d'une commande string running. nous utilisons _popen
au lieu de system
suggéré ci-dessus
#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;
}

Sur mon système, il y a quatre fichiers lisibles par l'utilisateur contenant des vidages hexadécimaux d'informations de périphérique; deux d'entre eux sont tous des zéros, deux autres contiennent des informations sur le disque et le DVD; Le DVD n'a pas de numéro de série et la série de disques commence à l'offset 0x20.
