I don't know that I'd agree that strlen is an example of the phenomenon you are talking about, but I also don't know that I could articulate why effectively. I do agree with your general point though. If you want an example that is obviously the same, the ALSA API[0] is about as textbook as it gets. Hell, it even names the first parameter "obj" in most of the functions for this particular subsection of functionality.
