clSetEventCallback substitute

Hi, I am trying to write a program where I get an asynchronous callback once a kernel has finished and I am stuck. May be a trivial thing (or not?) but I am running out of ideas. In OpenC...

Did you attempt to use clSetEventCallback() and the compilation failed because the API was missing or did you assume it would be missing? If it was the latter you might want to try it out, even though the supported API is 1.0 there are features from newer revisions mixed into it. I'm not sure myself if that API is present or not since I have never tried to use it before.

The Altera SDK doesn't support ICD which makes using a mix of SDKs very difficult. There is another post in this forum about that particular topic and I don't think it's worth exploring that method since it overcomplicates the host application assuming the workaround I posted actually works (not sure).

I did a search through the 1.0 spec and I don't see any way to create a callback mechanism triggered by the completion of the kernel execution.
