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.
