\section{Synopsis}
|
|
|
|
\File{\#include $<$libunwind.h$>$}\\
|
|
|
|
\Type{void} \Func{unw\_flush\_cache}(\Type{unw\_addr\_space\_t} \Var{as}, \Type{unw\_word\_t} \Var{lo}, \Type{unw\_word\_t} \Var{hi});\\
|

|
\section{Description}
|
|
|
|
The \Func{unw\_flush\_cache}() routine flushes all cached info as it
|
|
relates to address-range \Var{lo} to \Var{hi} (non-inclusive) in the
|
|
target address-space \Var{as}. In addition, all info cached for
|
|
address-space \Var{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
|
|
\Var{lo} and \Var{hi} should be understood as a hint:
|
|
\Func{unw\_flush\_cache}() may flush more information than requested,
|
|
but \emph{never} less. In other words, \Func{unw\_flush\_cache}() may
|
|
overflush, but not underflush.
|
|
|
|
As a special case, if arguments \Var{lo} and \Var{hi} are both 0, all
|
|
information cached on behalf of address space \Var{as} is flushed.
|
|
|
|
\section{Return Value}
|
|
|
|
The \Func{unw\_flush\_cache}() routine cannot fail and does not
|
|
return a value.
|
|
|
|
\section{Thread and Signal Safety}
|
|
|
|
The \Func{unw\_flush\_cache}() routine is thread-safe as well as safe to
|
|
use from a signal handler.
