9 The disk access API provides access to storage devices.
14 Since many disk devices (such as SD cards) are hotpluggable, the disk access
15 API provides IOCTLs to initialize and de-initialize the disk. They are
18 * :c:macro:`DISK_IOCTL_CTRL_INIT`: Initialize the disk. Must be called before
19 additional I/O operations can be run on the disk device. Equivalent to
22 * :c:macro:`DISK_IOCTL_CTRL_DEINIT`: De-initialize the disk. Once this IOCTL
24 the disk can be used for addition I/O operations.
26 Init/deinit IOCTL calls are balanced, so a disk will not de-initialize until
