error in ioctl call formatting floppy disk

*/ /* * As with hd.c, all routines within this file can (and will) be called * by interrupts, so extreme caution is needed. Seems there are problems with several drives. I should check for more errors, and do more graceful error * recovery. I've tried my best to get it working, * but I don't like programming floppies, and I have only one anyway. This makes some things easier (output_byte reset * checking etc), and means less interrupt jumping in case of errors, * so the code is hopefully easier to understand. Applications can use the standard control codes or device-specific control codes to perform direct input and output operations on a floppy disk drive, hard disk drive, tape drive, or CD-ROM drive.// SPDX-License-Identifier: GPL-2.0-only /* * linux/drivers/block/floppy.c * * Copyright (C) 1991, 1992 Linus Torvalds * Copyright (C) 1993, 1994 Alain Knaff * Copyright (C) 1998 Alan Cox */ /* * 02.12.91 - Changed to static variables to indicate need for reset * and recalibrate. The types of control codes you can specify depend on the device being accessed and the platform on which your application is running. For a list of standard control codes included in the SDK documentation, see the Remarks section of DeviceIoControl. In addition, device drivers can define their own device-specific control codes. For example, a control code can ask a device driver to return information about the corresponding device, or direct the driver to carry out an action on the device, such as formatting a disk.Ī number of standard control codes are defined in the SDK header files. Each control code represents an operation for the driver to perform. The DeviceIoControl function is a general-purpose interface that can send control codes to a variety of devices.

The DeviceIoControl function provides a device input and output control (IOCTL) interface through which an application can communicate directly with a device driver.
