void
unw_flush_cache(unw_addr_space_t
as,
unw_word_t
lo,
unw_word_t
hi);
The unw_flush_cache()
routine flushes all cached info as it
relates to address-range lo
to hi
(non-inclusive) in the
target address-space as.
In addition, all info cached for
address-space as
that is not tied to a particular code-range is
also flushed. For example, the address of the dynamic registration
list is not tied to a code-range and its cached value (if any) is
flushed by a call to this routine. The address range specified by
lo
and hi
should be understood as a hint:
unw_flush_cache()
may flush more information than requested,
but never
less. In other words, unw_flush_cache()
may
overflush, but not underflush.
As a special case, if arguments lo
and hi
are both 0, all
information cached on behalf of address space as
is flushed.
The unw_flush_cache()
routine cannot fail and does not
return a value.
The unw_flush_cache()
routine is thread-safe as well as safe to
use from a signal handler.
