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).
