boost :: scoped_lock解锁

Question

我可以在超出scoped_lock范围之前解锁互斥锁吗？我怎么能这样做？

{boost::mutex::scoped_lock  lock(mutex);

if(conditionaA)
{
   if(conditionB)
   {
    //could I unlock here as I don't want to hold the lock too long.
    //perform calculation
   }

}
else
{

}

}//lock scope

谢谢.

Answer 1

是.

使用该unlock()方法.

{boost::mutex::scoped_lock  lock(mutex);

if(conditionaA)
{
   if(conditionB)
   {
    //could I unlock here as I don't want to hold the lock too long.
    lock.unlock(); // <--
   }

   //perform calculation

}
else
{

}

}//lock scope

Answer 2

是; 只需使用.unlock()成员函数.
