Missing creation of sub-buffers (Ch. 7 p. 255)

[GoogleCodeExporter]

In the source code listing on pages 254-256, which is supposed to demonstrate 
the use of clCreateSubBuffer(), the creation of the sub-buffers does not appear 
to be included. Only the main buffer is pushed onto the vector of buffers, 
although subsequent code references that vector as though it has numDevices 
elements.
