 · Call IoCallDriver to pass the request on to the lower driver. If IoCallDriver returns STATUS_PENDING, call the KeWaitForSingleObject routine to put the current thread into a wait state. The driver sets the routine's Object parameter to the address of the event object that was initialized in the call to KeInitializeEvent.  · The answer to that question is simple: The driver should use what is referred to as the Inverted Call Model. We first described this technique in The NT Insider back in January of www.doorway.ru?id= Using this technique is much easier than its fancy name makes it sound. ioctl based interfaces ¶. ioctl based interfaces. ioctl () is the most common way for applications to interface with device drivers. It is flexible and easily extended by adding new commands and can be passed through character devices, block devices as well as sockets and other special file descriptors. However, it is also very easy to get.

Input/Output Control (ioctl, in short) is a common operation, or system call, available in most driver categories. It is a one-bill-fits-all kind of system call. If there is no other system call that meets a particular requirement, then ioctl () is the one to use. Practical examples include volume control for an audio device, display configuration for a video device, reading device registers, and so on — basically, anything to do with device input/output, or device-specific operations.
