SVC_Handler for Cortex M0

Note: This was originally posted on 25th October 2012 at http://forums.arm.com

Hello

we are trying to find a short implementation for the SVCHandler interrupt.
I want to do exactly like described here, but then a working version for the Cortex-m0:

and here:

http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dai0179b/ar01s02s07.html

we have no experts at assembly and the only thing we need is to get the svc number and arguments.
But if someone can explain me how the svc handler works I would be greatly helped.
And maybe someone can point me in the right direction on how to return values : "[font=Verdana, Tahoma, Arial, Helvetica, sans-serif][size=2]Any return value must also be passed back to the caller by modifying the stacked register values[/size][/font]".

Thank you in advance!
