Howdy, Is there a guide to the dos and don'ts of C according to the seL4 verification process? I kinda remember reading a quick summary somewhere, but can't find it on the wiki. Maybe I read it in one of the papers? I certainly remember reading the moral equivalent of "lol no strings". ;-) Thanks, Jeff

It’s described in the original SOSP paper, but some of the restrictions may have been relaxed since, with improvements to the C parser. The main restriction beyond general good coding practice remains no passing of references to automatic variables. You’re right, an up-to-date description on the wiki would be useful. Gernot
