In addition, all info cached for 22 address-space \Var{as} that is not tied to a particular code-range is 23 also flushed. For example, the address of the dynamic registration 24 list is not tied to a code-range and its cached value (if any) is 25 flushed by a call to this routine. The address range specified by 26 \Var{lo} and \Var{hi} should be understood as a hint: 27 \Func{unw\_flush\_cache}() may flush more information than requested, 28 but \emph{never} less. In other words, \Func{unw\_flush\_cache}() may 29 overflush, but not underflush. 30 31 As a special case, if arguments \Var{lo} and \Var{hi} are both 0, all 32 information cached on behalf of address space \Var{as} is flushed. 33 34 \section{Return Value} 35 36 The \Func{unw\_flush\_cache}() routine cannot fail and does not 37 return a value. 38 39 \section{Thread and Signal Safety} 40 41 The \Func{unw\_flush\_cache}() routine is thread-safe as well as safe to 42 use from a signal handler. 43 44 \section{See Also} 45 46 \SeeAlso{libunwind(3)}, 47 \SeeAlso{unw\_set\_caching\_policy(3)} 48 49 \section{Author} 50 51 \noindent 52 David Mosberger-Tang\\ 53 Email: \Email{dmosberger (a] gmail.com}\\ 54 WWW: \URL{http://www.nongnu.org/libunwind/}. 55 \LatexManEnd 56 57 \end{document} 58
