Problem creating listing file of LanMan directory

I’m trying to create a text file of all the filenames on a LanMan drive. I’m searching through each folder, starting from the root, using OS_GBPB 10. On reaching a directory, I stack the location and go through that directory. Etc.

However, in the root directory there is a directory called “lost+found”. OS_GBPB complains of “Access denied”, error 91828 (decimal). But the offset in R4 to the next item is not incremented. As far as I can see, this either takes me into an infinite loop, or requires me to stop the search there; I tried incrementing the pointer by 1 myself, but it didn’t appear to help.

Have I missed something? Is there a solution or a better way?

If I can get past this problem with access denied to a directory, there are also a couple of files that will, I believe, also come up as access denied.

Does count count all the files or find find a file you can’t reach?

If enumeration with OS_GBPB 10 stopped at an inaccessible directory in the root dir, you wouldn’t be able to open a Filer window on $?

You could examine the object attributes returned by OS_GBPB 10 to see if the file is accessible or the directory may be descended into.

How many objects at a time are you fetching? Try reading 1 object at a time. If you already are, try reading more at a time.

If the Filer shows to content of the root directory, you can try it the same way it does: allocates a buffer, try to read all items in the folder, if the buffer is too small, double the size and retry till the buffer is large enough.

Have you tried !Cat – one of its options is to produce a list of all the files on a disc?

Also what happens if you try *cat { > sdfs::0.$.file }

Note !Cat and *cat are completely different things!
