You can of course use setjmp & longjmp in C but depending on how many levels
up you jump they could be more trouble than they're worth. I think I've only
ever used them once.

That's makes a lot of work and it's really ugly. And you need global
jump_buf-s for that.

Its no different to C++ exceptions except obviously no destructors are called
so there's no chance to do a tidy up at each stack level. Also jumps arn't
limited to lower to higher stack frames jumps, they can jump about all over
the place. Whether thats useful or not I can't say. I've never needed it.
