NAME
- -
- - setjmp, longjmp, notejmp – non-local goto
- -
-

SYNOPSIS
- -
- - #include <u.h>
- #include <libc.h> -
- - int    setjmp(jmp_buf env) -
- - void longjmp(jmp_buf env, int val) -
- - void notejmp(void *uregs, jmp_buf env, int val)
- -
-

DESCRIPTION
- -
- - These routines are useful for dealing with errors and interrupts - encountered in a low-level subroutine of a program. -
- - Setjmp saves its stack environment in env for later use by longjmp. - It returns value 0. -
- - Longjmp restores the environment saved by the last call of setjmp. - It then causes execution to continue as if the call of setjmp - had just returned with value val. The invoker of setjmp must not - itself have returned in the interim. All accessible data have - values as of the time longjmp was called. -
- - Notejmp is the same as longjmp except that it is to be called - from within a note handler (see notify(3)). The uregs argument - should be the first argument passed to the note handler. -
- - Setjmp and longjmp can also be used to switch stacks.

BUGS
- -
- - -
- - Notejmp cannot recover from an address trap or bus error (page - fault) on the 680x0 architectures. -
- - To avoid name conflicts with the underlying system, setjmp, longjmp, - notejmp, and jmp_buf are preprocessor macros defined as p9setjmp, - p9longjmp, p9notejmp, and p9jmp_buf; see intro(3). -
- - P9setjmp is implemented as a preprocessor macro that calls sigsetjmp - (see Unix’s setjmp(3)).
