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).
