On some platforms, the file lock is advisory, which means that unless an application checks for a file lock, it will not be prevented from accessing the file. On other platforms, the file lock is mandatory, which means that a file lock prevents any application from accessing the file. In other words, how file locking behaves is platform-dependent. In your shoes I would write a test program to determine whether or not "rw" automatically locks the file. If it doesn't, then I would write the locking code as shown in the article and rerun the experiment. -- Kevin Dean [TeamB] Dolphin Data Development Ltd. http://www.datadevelopment.com/ NEW WHITEPAPERS Team Development with JBuilder and Borland Enterprise Server Securing Borland Enterprise Server http://www.datadevelopment.com/papers/index.html Please see Borland's newsgroup guidelines at http://info.borland.com/newsgroups/guide.html
