Hi,
you can place Objects into given memory space using the "new placement
syntax" (google-ready).
You have simply to add the following "method" to a class (or struct):
class Placeable {
public:
//...
void* operator new( size_t, void* buf ) { return buf; }
//...
};
this "method" is the overriden new-operator with placement semantics.
For instantiation you have to write:
extern void* address; // your memory section
Placeable* placed = new (address) YourStruct(/*constructor arguments if
any*/); // constructor with arguments
Placeable* placed = new (address) YourStruct; // constructor without
arguments
note you must not use the delete-operator on the object created by
overriden new.
for clenup (if needed) you have to define a destructor that you call
explicitly:
placed->Placeable::~Placeable();
Good luck,
Wolf Peuker
