Yes, thanks for the correction.

I had trouble getting the file name from the event. I think it's 
because the inotify module has name defined as char[0]. So I did 
this, which prints the name by using the extra data beyond the 
inotify_event struct itself:


     void* buf = GC.malloc(bufsiz);

     /* wait for an event to occur */
     size_t readlen = read(inotfd, buf, bufsiz);
     inotify_event* event = cast(inotify_event*) (buf);

     /* process event struct here */
     writeln("Received inotify event:");
     writeln("Bytes read: ", readlen);
     writeln("Length: ", event.len);
     writeln("Name:", cast(char[])(buf[event.len..readlen]));
