Possible counter-example:

   int counterexample(...)
   {
     ... other stuff ...

     switch (yyy) {
       case x:
          ... other stuff ...
	  goto err_ret;
       case y:
	  ... other stuff ...
	  goto err_ret;
       case other-stuff:
	  ... other stuff ...
	  break;
	  ...
       }

       return 0;		/* no need to close file;  return success */

     common:
       errno = last_error;/* save latest error for caller's sake */
       if (last_error != CE_NOFILE)
         fclose(f);		/* close file if still open */
       return -1;		/* return error code */
   } /* counterexample() */
