The existing template kernel sample is written in C , though not pure C.
Could you be a little more specific on what you are looking for?
The rest of our code is written in C. I would just like to have one openCL example (e.g. the "Template" example in the SDK openCL sample) written in ansi C, instead of C++. I guess I can just look up the header files, but nonetheless, an explicit example is useful.
