Monolithic, non stream-interface, onboard Device Driver

I would like to create a Monolithic, non stream-interface, onboard
Device Driver. It doesn't fit any of the Device Classes that exist
for CE, and so I would like to provide a simple interface (non
stream-interface). How do I go about it and how do I provide the
interface for application developers? Is this essentially a "service"?
Even so, how do I export an API as part of a custom SDK via the SDK
export capability? I am having difficulty finding references to doing
this.

Thanks

You make a stream driver and provide a wrapper library for applications to
use that ultimately calls the stream interfaces (CreateFile,
DeviceIoControl, CloseHandle) this is typically how it's done.

To include the lib and headers in the SDK just configure the SDK and use the
additional files tab to add the files needed into the SDK.

Thanks Steve, I was hoping there was a "cleaner" way. But I don't
suppose it will be too difficult. Is there a Stream Driver shell
(minimal implementation) in the tree anywhere?

The RAMDISK sample driver is a fairly simple one and the system.c file
contains the required entry points.

Or you could just build a DLL with whatever interface you want and call it a
'driver'. You'll have to deal with some special cases, like what happens
when multiple applications try to access the functions at the same time...

Although it is centered on a service that runs in services.exe,
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnce50/html/implement_network_service.asp?frame=true
has a sample "finger server" that shows how to have a local app be able to
interface to the service (which looks just like a device driver as far as
DLL exports, apps calling it...).
