int
setjmp(
label_t *label
)
void
longjmp(
label_t *label
)
)
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).
