/************************************************************************
*
* ramdev.c -- Skeleton device code.
*
* A sample 4 unit ramdisk that can be bound to an expansion slot device,
* or used without.  Works with the Fast File System.
* This code is required reading for device driver writers.  It contains
* information not found elsewhere.
*
* This example includes a task, though a task is not actually needed for
* a simple ram disk.  Unlike a single set of hardware registers that
* may need to be shared by multiple tasks, ram can be freely shared.
* This example does not show arbitration of hardware resources.
*

v51.1 changes (Fredrik Wikstrom):
 - is now an OS4 device
 - uses CreateTask()/DeleteTask() as opposed to setting up the Task structure (stack, etc.) manually
 - supports the NSCMD_DEVICEQUERY command (reports itself as a trackdisk type device)

Hopefully this will make it easier for people to write device drivers for OS4...
