cutil, why isn't there any documentation about it

I’ve been going over the SDK for the past few days. I have found the documentation of CUDA and the accompanying examples to be quite sufficient for a beginner. However, almost all the SDK examples use cutil functions. I have not been able to find any documentation for these functions. Can someone please point me in the right direction. Also, you can write CUDA code without the cutil functions. Can someone please tell me the advantage of these functions. Thanks.

cutil is just a helper library that was used to write the SDK examples. It doesn’t really have anything to do with CUDA other than being used by the developers of the SDK. It is not recommended that you use CUTIL in the same way that it is not recommended that you copy code directly from an SDK application into your own app. It was meant to demonstrate the features of CUDA, not to be production quality.

ok, that makes sense. thank-you.
