Hi,
need to synch file access to a file created by another app. The idea here is
to use mutually exclusive file locking where the creator opens/creates,
writes and closes and the reader waits for access and then opens
exclusively. When the reader is ready, the file should be removed and the
writer then recreates the file next time.

It is this Open-then-delete part in the reader app. that I am wondering
about. How can I open, close, delete without any access time gaps here? One
idea is to rename the file, assuming the rename function is lock aware but
there is only a STDIO function called "rename" available as i seems. Will
this function do or do you have any other ideas?

Thanks
