Rather than casting, lets do this the proper way and use a union.  After 
all this is better programming practice and avoids potential aliasing 
problems.  (Not that there should be in this particular case, but it 
never hurts to do the right thing).  ie:

   union foo {
     int i;
     void * p;
   } block [2];
   block[0].p = path;
   block[1].i = strlen (path);

Cheers
