Or, even easier, check to see if this is the object the spec_proc is
atteched to, by use of "me".

in the top line of the proc:

  struct obj_data *invis_obj = (struct obj_data *)me;
/* cast the "me" pointer to struct obj_data, and assign it to invis_obj */
  if (invis_obj->carried_by != ch)
/* check to see if the person carrying the invis_obj is the character
issuing the command, if not exit the proc */
        return 1;

Or whatever.
