SETJMP(9)						   BSD Kernel Developer's Manual						 SETJMP(9)

NAME
     setjmp, longjmp -- non-local jumps

SYNOPSIS
     #include <machine/types.h>
     #include <sys/systm.h>

     int
     setjmp(label_t *label);

     void
     longjmp(label_t *label);

DESCRIPTION
     The 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).
