问题描述
如何摆脱波动性？我应该使用哪个c ++风格的转换？
解决方案
使用 const_cast / p>
例如，
volatile sample * pvs = new sample ;
sample * ps = const_cast< sample *>（pvs）; //抛弃volatile-ness
也就是说， const_cast 用于丢弃常量和易失性。不幸的是，它的名称不包含术语volatile。也许，这是因为关键字 const 在使用中比关键字 volatile 更常见。
How to cast away the volatile-ness? Which c++ style cast should I use?
解决方案
Use const_cast.
For example,
volatile sample *pvs = new sample();
sample *ps = const_cast<sample*>(pvs); //casting away the volatile-ness
That is, const_cast is used to cast away both const-ness as well as volatile-ness. Unfortunately, it's name doesn't contain the term "volatile". Maybe, that is because the keyword const is more common in use than the keyword volatile.
