Outside of the current function, yes. Anywhere, no.
Longjmp allows you to return to places you’ve already been and have saved with setjmp. Also attempting to longjmp to a function that has since returned is undefined behavior. Thus longjmp’s usual use case is like exceptions in other languages, going back up the call chain, skipping intermediate functions.
