Previously, the WDK was known as the Driver Development Kit (DDK) [4] and supported Windows Driver Model (WDM) development. It got its current name when Microsoft released Windows Vista and added the following previously separated tools to the kit: Installable File System Kit (IFS Kit), Driver Test Manager (DTM), though DTM was later renamed and removed from WDK again.
The interfaces are IOCTL_SCSI_PASS_THROUGH and IOCTL_SCSI_PASS_THROUGH_DIRECT. Applications can build a pass-through request and send it to the device by using this IOCTL. SPTI is accessible to Windows software using the DeviceIoControl Windows API. [2] ImgBurn offers SPTI as a method for accessing optical disc drives. [3]
For example, on Win32 systems, ioctl calls can communicate with USB devices, or they can discover drive-geometry information of the attached storage-devices. On OpenBSD and NetBSD , ioctl is used by the bio(4) pseudo-device driver and the bioctl utility to implement RAID volume management in a unified vendor-agnostic interface similar to ifconfig .
Non-random data is harmless, because only a privileged user can issue the ioctl needed to increase the entropy estimate. [ dubious – discuss ] The current amount of entropy and the size of the Linux kernel entropy pool, both measured in bits, are available in /proc/sys/kernel/random/ and can be displayed by the command cat /proc/sys/kernel ...
Read-copy-update insertion procedure. A thread allocates a structure with three fields, then sets the global pointer gptr to point to this structure.. A key property of RCU is that readers can access a data structure even when it is in the process of being updated: RCU updaters cannot block readers or force them to retry their accesses.
Python added support for SocketCAN in version 3.3. [2] An open source library python-can provides SocketCAN support for Python 2 and Python 3 [3] [circular reference]. Installing a CAN device requires loading the can_dev module and configuring the IP link to specify the CAN bus bitrate, for example:
ethtool consists of two components, an API within the Linux kernel through which NICs can send and receive parameters through their device driver software, and a userspace API based on the Linux SIOCETHTOOL ioctl mechanism through which application programs can communicate with the kernel to send and receive NIC and NIC driver parameters.
There are also special files in DOS, OS/2, and Windows. These special files allow an application program to interact with a device by using its device driver via standard input/output system calls . Using standard system calls simplifies many programming tasks, and leads to consistent user-space I/O mechanisms regardless of device features and ...
