UNW_FLUSH_CACHE(3)           Programming Library            UNW_FLUSH_CACHE(3)


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.
