I'm trying out VFS for the first time and having a little trouble iterating
through files in a volume. Using code such as the following (and also code
that opens and reads files) I always find that the last file created in
external memory is missed. So, in the case of the snippet below, the count
is always 1 less than the number of files and in the case where I'm opening
files and performing operations on them the one most recently created is
unavailable. Probably something I don't understand about how the iterator
works?
FWIW, these are .wav files created by the Sony Voice Recorder application,
which my application starts and stops using virtual button presses on the
hardware Record button. The file that is being missed in this loop shows up
in the list of files in the Voice Recorder application before my app
terminates it. And it can be seen by browsing the directory right after it's
created.
error = VFSFileOpen(gVolRefNum, dirPathStr, vfsModeReadWrite, &dirRef);
if (!error) {
// initializations
counter = 0;
dirEntryIterator = vfsIteratorStart;
info.nameP = nameInit;
info.nameBufLen = 25;
// enumerate the volume
error = VFSDirEntryEnumerate(dirRef, &dirEntryIterator, &info);
if (!error) {
// count the files in the volume
while (dirEntryIterator != vfsIteratorStop){
counter++;
error = VFSDirEntryEnumerate(dirRef, &dirEntryIterator, &info);
if (error) ErrAlert(error);
}
} else {
ErrAlert(error);
}
} else {
ErrAlert(error);
}
VFSFileClose(dirRef);
TIA for any help you folks can provide.
David
