UNW_FLUSH_CACHE(3libunwind)  Programming Library   UNW_FLUSH_CACHE(3libunwind)

NAME
       unw_flush_cache -- flush cached info

SYNOPSIS
       #include <libunwind.h>

       void unw_flush_cache(unw_addr_space_t as, unw_word_t lo, unw_word_t
       hi);

DESCRIPTION
       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.

RETURN VALUE
       The unw_flush_cache() routine cannot fail and does not return a value.

THREAD AND SIGNAL SAFETY
       The unw_flush_cache() routine is thread safe as well as safe to use
       from a signal handler.
