Re: How to "reset" an object

Let's say I have a struct as follows:

[code]
struct MyStruct{

    int a;

    double b;

    std::string str;

};
[/code]

And let's say I create a global object of it which has all of its
members (including the intrinsic-type members) default-initialised:

[code]
MyStruct g_obj = MyStruct();
[/code]

Half-way through my program's execution, I want to "reset" this global
object. By "reset", I mean I want all of its member to go back to the
state that they were in when the "g_obj" object was initially created.
I achieve this with the following function:

[code]
template<class T>
void ResetObject(T &obj)
{
    obj.~T(); /* Destruct */

   ::new(&obj) T(); /* Construct */
}
[/code]

This works fine for a struct/class object. However, I want this
template function to work for any kind of object, be it an intrinsic
or an array.
