+<h3>DESCRIPTION</h3>
+<p>
+The <strong>vm_statistics</strong> structure defines the statistics
+available on the kernel's use of 
+virtual memory.  The statistics record virtual memory usage since
+the kernel was booted.
+<p>
+For related information for a specific task, see the <strong>task_basic_info</strong>
+structure.
+<h3>NOTES</h3>
+<p>
+This structure is machine word length specific because of the memory sizes
+returned.
