.TH "UNW\\_FLUSH\\_CACHE" "3" "02 December 2016" "Programming Library " "Programming Library "
.SH NAME
unw_flush_cache
\-\- flush cached info
.PP
.SH SYNOPSIS
.PP
#include <libunwind.h>
.br
.PP
void
unw_flush_cache(unw_addr_space_t
as,
unw_word_t
lo,
unw_word_t
hi);
.br
.PP
.SH DESCRIPTION
.PP
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 \fInever\fP
less. In other words, unw_flush_cache()
may
overflush, but not underflush.
.PP
As a special case, if arguments lo
and hi
are both 0, all
information cached on behalf of address space as
is flushed.
.PP
.SH RETURN VALUE
.PP
The unw_flush_cache()
routine cannot fail and does not
return a value.
.PP
.SH THREAD AND SIGNAL SAFETY
.PP
The unw_flush_cache()
routine is thread\-safe as well as safe to
use from a signal handler.
