### Sample Pen Device Driver

The Pen for OS/2 component of IBM Developer Connection Device Driver Kit for OS/2 contains a sample pen device driver that uses all the Pen for OS/2 system extension interfaces and implements the semantics of all the API functions. You need only modify the device-specific sections of the example code.

You can implement the pen device driver and meet the architected interfaces in any fashion. The sample pen device driver can help you get your pen hardware product working with Pen for OS/2. It also minimizes the experience you must have in developing OS/2 device drivers and Workplace Shell objects.

The following sections give an overview of the sample pen device driver. Each subcomponent has additional information in its routine entry-point comments and module prolog comments.
