}delete[] and aliasing questions
Author
1) Can I just do a delete obj3D or do I need to delete[] the members first, then delete the whole object?
2) Is it possible to alias so I don''t end up with something like:
instead of.. object->face->obj[3].vx
have.. of[3].vx
?
if you have an object:
you must delete the memory you allocated in this object. if you
don''t do, you have a memory leak:
you could do this by defining a destructor, i think:
struct obj{ int *ptr; obj () { ptr = new int[32]; }}you must delete the memory you allocated in this object. if you
don''t do, you have a memory leak:
obj *o_ptr = new obj (); // allocationdelete [] o_ptr->ptr; // deallocationdelete o_ptr; // deallocationyou could do this by defining a destructor, i think:
obj::~obj (){ if (ptr) { delete [] ptr; ptr = (int *)0; }}
You should give your struct a destructor to call delete[] on each of those pointers. That way your class can simply call delete on the struct and it will carry through to delete the pointers.
Look up references (AKA aliases, now there''s a pun 
).
