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 under- flush. 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.
