Hello,  
I am new to using the “namespace” declaration without an actual name added.  
Perhaps someone can please explain this? here is the example I don’t quite understand:

namespace Abc  
{  
namespace  
{  
BasicFuncitons::Demo GetSetup()  
{  
what’s the deal with this “dangling” namespace declaration and no label?  
is this common?  
Thanks!  
MD

Not certain, but a reasonable guess: it is resetting it to the “default” namespace that you would have if there were no namespace set explicitly.
