CPP: Windows: DeviceIoControl An application can use the DeviceIoControl function to perform direct input and output operations on, or retrieve information about, a floppy disk drive, hard disk drive, tape drive, or CD-ROM drive. The following example demonstrates how to retrieve information about the first physical drive in the system. It uses the CreateFile function to retrieve the device handle to the first physical drive, and then uses DeviceIoControl with the IOCTL_DISK_GET_DRIVE_GEOMETRY control code to fill a DISK_GEOMETRY structure with information about the drive.
