Banned C standard library functions in Git source code
I&#x27;m glad to see that setjmp() and longjmp() are still allowed.<p>I&#x27;m just kidding by the way. For those C programmers who  haven&#x27;t encountered these before, it is a powerful way to do a &quot;goto&quot; in C. Powerful in the sense that you can jump anywhere, not limited to the same function. If it&#x27;s used at all these days, it&#x27;s used for exception handling.<p>More info:
