+
+This is a descriptor class which provides a buffer of fixed length, allocated
+on the heap, for containing and accessing data.
+
+The class is intended for instantiation.
+
+Heap descriptors have the important property that they can be made larger
+or smaller, changing the size of the descriptor buffer. This is achieved by
+reallocating the descriptor. Unlike the behaviour of dynamic buffers, reallocation
+is not done automatically.
+
+Data is intended to be accessed, but not modified; however, it can be completely
+replaced using the assignment operators of this class. The base class (TDesC16) provides
+the functions through which the data is accessed.
+
+The descriptor is hosted by a heap cell, and the 16-bit data that the descriptor
+represents is part of the descriptor object itself. The size of the cell depends
+on the requested maximum length of the descriptor buffer when the descriptor
+is created or re-allocated.
+
+It is important to note that the size of the allocated cell, and, therefore,
+the resulting maximum length of the descriptor, may be larger than requested
+due to the way memory is allocated in Symbian OS. The amount by which this
+may be rounded up depends on the platform and build type.

+16 bit resizable buffer descriptor.
+
+The class provides a buffer that contains, accesses and manipulates
+TUint16 data. The buffer itself is on the heap, and is managed by the class.
+
+Internally, RBuf16 behaves in one of two ways:
+
+- as a TPtr16 descriptor type, where the buffer just contains data
+- as a pointer to a heap descriptor, an HBufC16* type, where the buffer
+ contains both descriptor information and the data.
+
+Note that the handling of the distinction is hidden from view.
+
+An RBuf16 object can allocate its own buffer. Alternatively, it can take
+ownership of a pre-existing section of allocated memory, or it can take
+ownership of a pre-existing heap descriptor. It can also reallocate the buffer
+to resize it. Regardless of the way in which the buffer has been allocated,
+the RBuf16 object is responsible for freeing memory when the object itself is closed.
+
+The class is intended for instantiation.
+
+The class is derived from TDes16, which means that data can be both accessed
+and modified. The base classes provide the functions through which the data is
+accessed. In addition, an RBuf16 object can be passed to any function that is
+prototyped to take a TDes16 or a TDesC16 type.
