 2             Trivial virtual file system for cabinet conformance test.
 3             
 4             Provides versions of the filesystem calls needed by cabinet:
 5             open, read, write, lseek, close.  Each returns the same
 6             return values as the corresponding _open, _read, _write, _lseek, _close
 7             calls in Win32, i.e. on error, they return -1,
 8             and on success, open returns a file handle,
 9             read and write return # of bytes transferred,
10             seek returns the position,
11             and close returns 0.
12             
13             Also provides functions for creating whole files from binary arrays,
14             and comparing whole files to binary arrays.
