-//========================================class declaration CIRBufferContainer============================================

-/**
- * This class is wrapper class which can hold an address of a memory chunk
- * and size (granularity) of memory chunk.
- * This is implemented so as to use with queue like TSglQue
- * iLink is public member and is of a member of type TSglQueLink
- * The memory address is of TUint8* type and address is of type TInt
- * you can assign the address and granularity only when you create an instance
- * and retrive address and size using Des() and GetSize() respectively
- * typical usage is as follows
- * Note: This class DOESN'T take any responsibility of removing memory chunk
- * associated to it when you delete the chunk, since it is not creating the memory
- * chunk it doesn't do deallocation it has to taken care from where you create
- * the memory chunk
- *
- * @code
- *
- * TSglQue<CIRBufferContainer> Myque;
- * TInt f_off = _FOFF(CIRBufferContainer,iLink);
- * Myque.SetOffset(f_off);
- * TUint8* buffer;
- * TInt sizeofbuffer;
- * CIRBufferContainer* bufferholder;
- * bufferholder = CIRBufferContainer::NewL(buffer,sizeofbuffer);
- * Myque.AddLast(*bufferholder);
- * TUint8* ptr = bufferholder->Des();
- * TInt size = bufferholder->GetSize();
- * bufferholder = Myque.First();
- * Myque.Remove(*bufferholder);
- * delete bufferholder; //deleting bufferholder doesn't deletes memory allocated
- * //to buffer is not getting deleted we have delete it explicitly
- *
- * delete buffer;
- *
- * @endcode
