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

DESCRIPTION

       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.

       found.
