SETJMP(9) FreeBSD 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).
