When the activate_func() will be invoked? is it a callback function or
something?. I don't know why and how you implemented that, but you
already retrieved filename in open_file(), if you supposed to call
activate_func() here, you can pass the filename to activate_func(),
the activate_func() much or less will be;

static void activate_func(const char *filename)
{
   FILE *fop = fopen(filename, "a" );
   /* Verify and work with it */
}

then call activate_func(filename) in open_file()

You can't fopen(open_file( *widget, data,filename),"a") because it is
a programming error, peoples in this list usually will not happy to
answer this.
