Returns information about the geometry of floppy drives.
None.
None.
The driver returns an array of DISK_GEOMETRY records for the types of media it supports in the buffer at Irp->AssociatedIrp.SystemBuffer.
Parameters.DeviceIoControl.OutputBufferLength in the I/O stack location of the IRP indicates the size, in bytes, of the buffer, which must be at least (NumberOfSupportedMediaTypes * sizeof(DISK_GEOMETRY)).
The Information field is set to the size, in bytes, of the returned data. The Status field can be set to STATUS_SUCCESS, or possibly to STATUS_INVALID_DEVICE_REQUEST, STATUS_BUFFER_TOO_SMALL, or STATUS_BUFFER_OVERFLOW.
Retrieves the geometry information for the device.
To perform this operation, call the DeviceIoControl function with the following parameters.
BOOL DeviceIoControl(
(HANDLE) hDevice, // handle to device
IOCTL_STORAGE_GET_MEDIA_TYPES, // dwIoControlCode
NULL, // lpInBuffer
0, // nInBufferSize
(LPVOID) lpOutBuffer, // output buffer
(DWORD) nOutBufferSize, // size of output buffer
(LPDWORD) lpBytesReturned, // number of bytes returned
(LPOVERLAPPED) lpOverlapped // OVERLAPPED structure
);
Irp->IoStatus.Status is set to STATUS_SUCCESS if the request is successful.
Otherwise, Status to the appropriate error condition as a NTSTATUS code.
For more information, see NTSTATUS Values.
This device I/O control operation is for all class drivers, as well as non-SCSI hard drives and floppy disk devices.
