|
* Creates an encapsulation of a T array which will be automatically deleted when this object goes out of scope.
|
|
* This is a simple buffer meant to be used only inside of a function and not moved around, with a few minor exceptions.
|
|
* The internal buffer is allocated on the heap.
|
|
* The operator * has been overloaded to return the internal buffer. (or just use scoped_buffer.buffer if you wish to be explicit)
|
|
* The operator & was not used because I think it is stupid to do so.
|
|
* "*" on a reference is fine however since it isn't used to dereference in the case.
|
|
* @tparam T type that is stored in buffer eg char
