A meta comment on the comments on this article: as one might expect post-"goto fail"[1] there are a lot of people saying "hey this should be refactored, no goto!" I thought that at first when looking at the code, given what I remember of the Apple SSL vulnerability, and how "goto" has a smell. But, as it turns out, there are sane reasons to use goto in systems programming, especially as a kind of cleanup / finally block. TIL.

In plain c, goto is about the only sane way to do error handling in an ergonomic and easily maintainable way. The only cost is the goto stigma (which is generally justified).
