FSMakeFSSpecCompat(
short vRefNum,
long dirID,
ConstStr255Param fileName,
FSSpec * spec);
/*
The FSMakeFSSpecCompat function fills in the fields of an FSSpec record.
If the file system can't create the FSSpec, then the compatibility code
creates a FSSpec that is exactly like an FSSpec except that spec.name
for a file may not have the same capitalization as the file's catalog
entry on the disk volume. That is because fileName is parsed to get the
name instead of getting the name back from the file system. This works
fine with System 6 where FSMakeSpec isn't available.
vRefNum input: Volume specification.
dirID input: Directory ID.
fileName input: Pointer to object name, or nil when dirID specifies
a directory that's the object.
spec output: A file system specification to be filled in by
FSMakeFSSpecCompat.
Result Codes
noErr 0 No error
nsvErr -35 Volume doesn<73>t exist
fnfErr -43 File or directory does not exist
(FSSpec is still valid)

EXTERN_API( OSErr )
FSpOpenDFCompat(
const FSSpec * spec,
char permission,
short * refNum);
/*
The FSpOpenDFCompat function opens the data fork of the file specified
by spec.
Differences from FSpOpenDF: If FSpOpenDF isn't available,
FSpOpenDFCompat uses PHBOpen because System 6 doesn't support PBHOpenDF.
This means FSpOpenDFCompat could accidentally open a driver if the
spec->name begins with a period.
spec input: An FSSpec record specifying the file whose data
fork is to be opened.
permission input: A constant indicating the desired file access
permissions.
refNum output: A reference number of an access path to the file's
data fork.
Result Codes
noErr 0 No error
nsvErr -35 No such volume
ioErr -36 I/O error
bdNamErr -37 Bad filename
tmfoErr -42 Too many files open
fnfErr -43 File not found
opWrErr -49 File already open for writing
permErr -54 Attempt to open locked file for writing
