当我在Windows XP - 32上运行以下代码时,我得到以下结果.
我只插了一个usb笔式驱动器

我在互联网上搜索并找到了一些示例代码来尝试。
但我不确定它是否正确......
您能告诉我如何使用 IOCTL_MOUNTMGR_QUERY_POINTS 来获取驱动器号吗
感谢您的时间
下面是我的源代码
HANDLE hUsbDevice = CreateFile( pDetData->DevicePath,
GENERIC_READ | GENERIC_WRITE,
0, NULL, OPEN_EXISTING, 0, NULL);
UCHAR Bytes[10000];
PMOUNTMGR_MOUNT_POINTS pMntPoints = (PMOUNTMGR_MOUNT_POINTS) Bytes;
MOUNTMGR_MOUNT_POINT mntPoint, *pmnt;
DWORD bytesReturned;
if (hUsbDevice == INVALID_HANDLE_VALUE) {
qDebug()<<"CreateFile failed with error: %d\n"<<GetLastError();
}
else {
qDebug ()<<"VALID DEVICE";
BOOL status = DeviceIoControl( hUsbDevice,
IOCTL_MOUNTMGR_QUERY_POINTS,
&mntPoint,
sizeof(MOUNTMGR_MOUNT_POINT),
pMntPoints,
10000,
&bytesReturned,
NULL);
wprintf(L"\tBOOL VALUE : %d\n", status);
qDebug ()<<pMntPoints->MountPoints;
}
