Hi all You will find attached a implementation of fswatcher using the FAM API. It should link either with FAM (1) or gamin (2), which are available on different flavors of unix. The goal is to take advantage of existing facilities and getting rid of timers. FAM and gamin use kernel helpers to avoid polling when they can. The code probably has some bugs and I'm not sure I followed exactly the different notifications semantics but it's a start. I tested it with GWorkspace and it seems to work well. Opinions ?
The original fswatcher doesn't create a new Watcher object if there already is one for a path beeing added; it adds only a "listener", that is, it increments a counter. When, removing all listeners, the counter becomes 0, the Watcher object is removed from the watchers array.
Philippe NB : fswatcher parameter '--daemon' results in the opposite, or I am missing something ?
'--daemon' is not intended to be used from the command line; it is only an internal way to create a daemon using only NSTask instead of fork(); many GNUstep daemons does this; gdnc, gpbs, etc.
