13162	Sharable Lock And Upgradable Lock documentation	anonymous	Ion Gaztañaga	"http://www.boost.org/doc/libs/1_64_0/doc/html/interprocess/synchronization_mechanisms.html#interprocess.synchronization_mechanisms.sharable_upgradable_mutexes.sharable_upgradable_locks

 The documentation of the interprocess sharable and upgradable locks state that ""Boost.Interprocess mutexes are best used with the scoped_lock utility, and this class only offers exclusive locking."".
  Then goes on to explain to use sharable_lock and upgradable_lock. Then shows some examples; but the example for a timed lock is wrong or misleading:
{
   boost::posix_time::ptime abs_time = ...

   //This will call timed_lock_sharable()
   scoped_lock<SharableOrUpgradableMutex> lock(sh_or_up_mutex, abs_time);

   //Check if the mutex has been successfully locked
   if(lock){
      //Some code
   }
   //If the mutex was locked it will be unlocked
}

  The example basically says that the scoped_lock will acquire a sharable lock (saying that it will call timed_lock_sharable())!
  This should read ""sharable_lock<..."" instead of ""scoped_lock<..."" same with upgradable lock."	Bugs	new	To Be Determined	interprocess	Boost 1.64.0	Not Applicable		boost docs
