+// Purpose:     Driver API
+// Description: This file defines the API used by device drivers to access
+//              system services. When the kernel is present it maps directly
+//              to the Kernel C API. When the kernel is absent, it is provided
+//              by a set of HAL functions.
+//              
+// Usage:       #include <cyg/kernel/kapi.h>
