+that the Kernel provides. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p>The section begins with a discussion of the APIs for fundamental types
+such as buffers and arrays. Kernel side programs cannot use all of the same
+APIs as user-side programs, so you need to be aware of these restrictions,
+and the alternative APIs provided by the Kernel. </p>
+<p>The guide then discusses a number of idioms for communicating between different
+threads and processes, including Publish and Subscribe, Kernel-side messages,
+shared chunks, and environment slots. </p>
+<p>Some more advanced programming issues are then discussed, including how
+to design a device driver to behave correctly in a demand paged OS environment,
+in which client programs may not be continuously in memory, and how to integrate
+a device driver with system wide power resource management. </p>
+<p>The section ends with a discussion of how Kernel APIs encourage safe programming
+with the use of precondition checks. </p>
