FSSpec structure
#include <Files.h>
typedef struct FSSpec { Size Offset Description
short vRefNum; 2 0 volume reference number
long parID; 4 2 directory ID of parent directory
Str63 name; 64 6 filename or directory name
} FSSpec; 70
typedef FSSpec *FSSpecPtr;

typedef FSSpecPtr FSSpecArrayPtr;

Notes: The FSSpec record can describe only a file or a directory, not a volume. A
volume can be identified by its root directory, although the system software
never uses an FSSpec record to describe a volume. (The directory ID of the
root's parent directory is fsRtParID, defined in the interface files. The name
of the root directory is the same as the name of the volume.) Some of the
system software uses arrays of FSSpec records.
