A beginner question with poor English:
Here I got a void* param and want to cast(or change) it to a specific type. But I don't know which "casting symbol" to use.
Either**static_cast** and reinterpret_cast works.
I want to know which one is better? which one does the Standard C++ recommend?

typedef struct
{
    int a;
}A, *PA;

int foo(void* a)                // the real type of a is A*
{
    A* pA = static_cast<A*>(a); // or A* pA = reinterpret_cast<A*>(a);?
    cout<<pA->a<<endl;
    return 0;
}

Here I use

A* pA = static_cast(a);

or

A* pA = reinterpret_cast(a);

is more proper?
