	  struct {
	      char   *f_name;
	      int    (*f_func)();        /* if memory serves */
	  } stuff[] = {
	      {"fubar", fubar},
	              /* etc ..... */
	      {"blarg", blarg},
          }

    Then just search stuff[?].f_name for the function you want, and
    then do:  *(stuff[index].f_func)( args... );

    (It works faster if it is sorted by name so you can use a binary search.)
