In QNX4.25 I try to find some file by find utility and receive next message:

$ find / -name file_name -print
...
find: Cannot recurce into 'folder_name' - filesystem form an infinite loop
...
where 'folder_name' - is the full path to some folder, in which application record the data.

Inside this folder there is another folder with empty name (or without name). 

When I try to open noname folder then ezfm file manager jump to the filesystem root /.

I can't to delete this noname folder.

Please explain:

- what is the reason of produsing noname folder ?

- can chkfsys  utility recower filesystem infinite loop error?

Re: QNX4 filesystem infinite loop

I got this issue when I called the following C code:


open("?delta", O_RDWR | O_CREAT | O_TRUNC);

It was a bug on my part, but it created a nameless symlink to itself. I can't figure out how to delete or even rename it
.

Re: QNX4 filesystem infinite loop

Hi Andrew,

This code creates regular file on my system. It can be deleted by the following command:

# rm -f ?delta

What QNX version do you use?

Respectfully,
Oleg
