I think it /is/ C, but it isn't clear what the C means. This code doesn't break any of the rules of the C language which would cause it not to parse. Otherwise we wouldn't have got into this mess because it wouldn't compile.
[ Sadly I don't trust the Adobe developers enough to imagine that a diagnostic from static analysis would have stopped them doing this. I think "Warning: abuse of memcpy()" would have scrolled by with hundreds of other warnings they ignore... ]
In the same way "Don't frabidulate the wugs, she's my uncle" is an English sentence, but it isn't clear what it means. You can parse it, and you can answer some questions about it, e.g. "Are you being asked to frabidulate the wugs?" but there are big unknowns.
