SETJMP(9)              NetBSD 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).
