.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.

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

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