Let's write a setjmp

The more general POV is that "setjmp" defines a continuation and "longjmp" invokes it.

While the most frequent use of explicit continuations is for implementing exceptions, you are right that there are many other programming techniques based on explicit continuations.

I'm now wondering if anyone has written an actual continuation library in C (ie saving and restoring the whole stack). Is it possible?

Coroutines are one good example.
