Using the IOCTL_DISK_FORMAT_TRACKS control code formats a specified, contiguous set of tracks on a disk.
To perform this operation, call the DeviceIoControl function with the following parameters.
BOOL DeviceIoControl( (HANDLE) hDevice, // handle to device IOCTL_DISK_FORMAT_TRACKS, // dwIoControlCode operation (LPVOID) lpInBuffer, // input buffer (DWORD) nInBufferSize, // size of input buffer NULL, // lpOutBuffer; must be NULL 0, // nOutBufferSize; must be zero (LPDWORD) lpBytesReturned, // number of bytes returned (LPOVERLAPPED) lpOverlapped // OVERLAPPED structure );
If lpOverlapped is NULL (nonoverlapped I/O), lpBytesReturned is used internally and cannot be NULL.
If lpOverlapped is not NULL (overlapped I/O), lpBytesReturned can be NULL.
If hDevice was opened with the FILE_FLAG_OVERLAPPED flag, lpOverlapped must point to a valid OVERLAPPED structure. In this case, the operation is performed as an overlapped (asynchronous) operation. If the device was opened with the FILE_FLAG_OVERLAPPED flag and lpOverlapped is NULL, the function fails in unpredictable ways.
If hDevice was opened without specifying the FILE_FLAG_OVERLAPPED flag, lpOverlapped is ignored and DeviceIoControl does not return until the operation has been completed, or until an error occurs.
If the operation succeeds, DeviceIoControl returns a nonzero value.
If the operation fails, DeviceIoControl returns zero. To get extended error information, call GetLastError.
This device I/O control operation is for floppy disk devices only.
