Question

How to cast away the volatile-ness? Which c++ style cast should I use?

Answer 1

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, its name doesn’t contain the term “volatile”. Maybe, that is because the keyword const is more common in use than the keyword volatile. As one of the comment says, cv_cast would have been more appropriate name!
