setjmp, longjmp —
#include <machine/types.h>
#include <sys/systm.h>
int
  
  setjmp(label_t
    *label);
void
  
  longjmp(label_t
    *label);
setjmp() function saves its calling environment in
  label. It returns zero on success. The
  longjmp() function restores the environment saved by
  the most recent invocation of setjmp(). It returns so
  that kernel execution continues as if the corresponding invocation of the
  setjmp() had just returned.
setjmp() and
    longjmp() are a machine-independent interface for
    machine-dependent implementations.
These functions are primarily used by ddb(4).
