C++ has exceptions and having seen the vast majority of code and the way it’s written and the understanding of people writing it, exception safety is a foreign concept. Doing it in C without RAII seems particularly masochistic and doomed to fail.

And unwinding the stack isn’t what you want to do because you’re basically signaling you want to cancel the operation and you’re throwing all the state when you precisely don’t want to do that - you just want to pause the current task and do other I/O in the meantime.
