windows cplusplus 获取磁盘分区信息

可以使用Windows API函数来获取磁盘分区信息，以下是示例代码：

#include <iostream>
#include <windows.h>
#include <winioctl.h>

using namespace std;

int main()
{
    char drive[] = "\\\\.\\PhysicalDrive0"; // 磁盘编号，0为第一个物理磁盘
    HANDLE hDisk = CreateFileA(drive, GENERIC_READ, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
    if (hDisk == INVALID_HANDLE_VALUE)
    {
        cout << "Failed to open disk!" << endl;
        return 0;
    }

    STORAGE_PROPERTY_QUERY query;
    char buf[1024];
    memset(&query, 0, sizeof(query));
    memset(buf, 0, sizeof(buf));

    query.PropertyId = StorageDeviceProperty;
    query.QueryType = PropertyStandardQuery;

    if (!DeviceIoControl(hDisk, IOCTL_STORAGE_QUERY_PROPERTY, &query, sizeof(query), buf, sizeof(buf), NULL, NULL))
    {
        cout << "Failed to get disk property!" << endl;
        CloseHandle(hDisk);
        return 0;
    }

    STORAGE_DEVICE_DESCRIPTOR* desc = (STORAGE_DEVICE_DESCRIPTOR*)buf;
    char* vendor = (char*)buf + desc->VendorIdOffset;
    char* product = (char*)buf + desc->ProductIdOffset;
    char* serial = (char*)buf + desc->SerialNumberOffset;

    cout << "Vendor: " << vendor << endl;
    cout << "Product: " << product << endl;
    cout << "Serial Number: " << serial << endl;

    CloseHandle(hDisk);
    return 0;
}

该代码通过调用`CreateFile`函数打开磁盘设备，然后使用`DeviceIoControl`函数发送`IOCTL_STORAGE_QUERY_PROPERTY`命令获取设备属性，最后解析设备属性信息并输出到控制台上。
