I have seen CUDA_SAFE_CALL and CUT_SAFE_CALL in a lot of code examples, but I cant find anything that tells me what they are.

Can someone help me out?

NVIDIA_CUDA_SDK/common/inc/cutil.h has doxygen-style comments and will tell you exactly what they do (basic error checking in debug, nothing otherwise).

Ok…its in the Common project. I was looking in all the header files in the toolkit\include folder
