12 hi);

15 The unw_flush_cache() routine flushes all cached info as it relates to
16 address-range lo to hi (non-inclusive) in the target address-space as.
17 In addition, all info cached for address-space as that is not tied to a
18 particular code-range is also flushed. For example, the address of the
19 dynamic registration list is not tied to a code-range and its cached
20 value (if any) is flushed by a call to this routine. The address range
21 specified by lo and hi should be understood as a hint:
22 unw_flush_cache() may flush more information than requested, but never
23 less. In other words, unw_flush_cache() may overflush, but not under‐
24 flush.
25
26 As a special case, if arguments lo and hi are both 0, all information
27 cached on behalf of address space as is flushed.
28
30 The unw_flush_cache() routine cannot fail and does not return a value.
31
33 The unw_flush_cache() routine is thread-safe as well as safe to use
34 from a signal handler.
