Keyboard header file, kdb. Sample keyboard layouts.
To visualize the layout of a specific keyboard, see Windows Keyboard Layouts. The following table identifies the features supported across different client versions of the Windows operating system. Windows mouse drivers do not check the overflow bits. In case of overflow, the mouse should simply send the maximal signed displacement value. The ntddkbd. The sample Kbfiltr source code.
After Kbfiltr receives the hook keyboard request, Kbfiltr filters the request in the following way:. Kbdclass sends this request down the keyboard device stack before it opens the keyboard device. After Kbfiltr received the keyboard connect request, Kbfiltr filters the connect request in the following way:. If the request is not successful, Kbfiltr completes the request with an appropriate error status.
Kbfiltr provides a template for a filter service callback routine that can supplement the operation of KeyboardClassServiceCallback , the Kbdclass class service callback routine. The filter service callback can filter the input data that is transferred from the device input buffer to the class data queue. Note that a Plug and Play keyboard can be added or removed by the Plug and Play manager. For all other device control requests, Kbfiltr skips the current IRP stack and sends the request down the device stack without further processing.
Default keyboard initialization includes the following operations:. The following table identifies the features supported across different client versions of the Windows operating system.

Saves the upper-level information passed to Kbfiltr, which includes the context of an upper-level device object, a pointer to an initialization callback, and a pointer to an ISR callback.

Default keyboard initialization includes the following operations: reset the keyboard, set the typematic rate and delay, and set the light-emitting diodes LED.
A vendor can implement a filter service callback to modify the input data that is transferred from the device's input buffer to the class data queue. For example, the callback can delete, transform, or insert data. The ISR callback is optional and is provided by an upper-level mouse filter driver. Saves the upper-level information passed to Moufiltr, which includes the context of an upper-level device object and a pointer to an ISR callback.
For all other requests, Moufiltr skips the current IRP stack and sends the request down the device stack without further processing. A filter service callback can be configured to modify the input data that is transferred from the device's input buffer to the class data queue.
