Is there a way to exclusively lock a file to prevent other processes from reading it while we have it open? I need to cache some overflow data to disk in a temp file and I want to make sure no other processes can read the contents of this file while I'm using it. I tried the following using an 'append binary' mode, but I can use NotePad to read the file while I'm using it: fd = open( r'a-temp-file.dat', 'ab' ) My environment is Python 2.6.4 (32-bit) under Windows, but I'm looking for a cross-platform solution if that's possible.
Have a look at tempfile.mkstemp() in the standard library. -- http://mail.python.org/mailman/listinfo/python-list
