       *traddr , const char *trsvcid , const char *subsysnqn , const char  *host_traddr  ,  const
       char *host_iface );

       Lookup  a controller in s based on transport, traddr, trsvcid, subsysnqn, host_traddr, and
       host_iface. transport must be specified, other fields may be  required  depending  on  the
       transport. Parameters set to NULL will be ignored.

       controller cannot be found.
