c++ - Is there a boost equivalent to this "safe

i new boost threading (came win32 threading, has ruined me).

so i'm trying make more "raii" way check working loop should still going. made simple function:

template<typenamet>  t safe_read(const t& t,boost::mutex& mutex) {     boost::interprocess::scoped_lock lock(mutex);     return t; }

is there boost equivalent this, since seems i'd use time? acceptable call?

the idea able safely without using weirder lock:

while(!safe_read(this->is_killing_,this->is_killing_mutex_)) {     dowork(); }

boost::atomic<bool> added in boost v1.53.0, based on c++11 std::atomics. example:

#include <boost/atomic.hpp>  boost::atomic<bool> is_killing (false);  while (!is_killing) { }

this eliminate explicit mutex , safe_access function code, providing synchronization required.
