File Streaming Size and Existence

[Greg Bungo]

Hello,

I'm trying to use the File Streaming API to determine whether
a file exists, and if so, what its size is.  I am doing this so I
can decide whether to create/overwrite a file.

I have tried several methods, and all give disturbing error
messages in POSE.

1. 
lLen = sizeof ( Boolean );
fErr = FileControl( fileOpGetCreatedStatus, fStream,
  &bValue, &lLen );
if (bValue) . . .
    then supposedly the file was just created.  But POSE
    gives this message:

        "...has just read directly from an unallocated chunk
         of memory."

2.
fStream = FileOpen( 0, PROGRAM_INI_FILE, 0, 0,
      (fileModeReadOnly | fileModeExclusive), &fErr );
if (! fStream)  return fErr;
fErr = FileSeek( fStream, 1, fileOriginBeginning );

If fErr is set to fileErrEOF, then the file is has no bytes, and
can be safely overwritten.

But again, POSE says that my program:

        "...has just read directly from an unallocated chunk
         of memory."

3.
fStream = FileOpen( 0, PROGRAM_INI_FILE, 0, 0,
      (fileModeReadOnly | fileModeExclusive), &fErr );
if (! fStream)  return fErr;
fErr = FileEOF( fStream );

Again, the same message from POSE.

Please tell me what is the best method for determining
file existence and size.  Something like the Unix stat()
function would be ideal.

Thanks,
