[gamin] Does gamin really work?

[Daniel Eriksson <daner964 student liu se>]

Hi.
I'm quite new in using fam/gamin, so I hope I'm not doing something very
wrong. I just can't get gamin to notice any changes I do to the
monitored files. I have a program that sets up monitoring (using
FAMMonitorDirectory()) of some directories and then calls FAMPending to
check if anything has changed using the following loop (where fc is my
FAMConnection):

      FAMEvent fe;
      while(FAMPending(&fc)) {
        if (FAMNextEvent(&fc, &fe) < 0)
          {
            perror("FAMNextEvent");
            exit(1);
          }
        printf("%-24s %i\n", fe.filename, fe.code);
      }

As you can see in my attached logfiles (created using the directives on
Gamin homepage) I get the initial FAMExists and FAMEndExist events, but
after that it doesn't matter what I do (i e making new files, removing
files etc) in the monitored directories, I get no more events. Is this
me doing something very wrong or is it Gamin not working?

I use Gamin 0.0.24 (Fedora Rawhide rpm). The monitored directories is on
vfat partitions, but that shouldn't pose any problem, should it?
