Convert native byte array (pointer) to managed byte[]

[Dave]

We are writing some code to interface to a DLL. The DLL
has a callback method that returns the address of a byte
buffer and the buffer length. I have defined the byte
pointer as an IntPtr.

How do I convert between the IntPtr and my managed byte[]
that I want to copy the data into???
