As a result, +a failure, such as if the connection is refused, will be returned +immediately, and no further action will be taken. + +However, if the special value `NNG_FLAG_NONBLOCK` is +supplied in _flags_, then the connection attempt is made asynchronously. + +Furthermore, if the connection was closed for a synchronously dialed +connection, the dialer will still attempt to redial asynchronously. + +TIP: While `NNG_FLAG_NONBLOCK` can help an application be more resilient, +it also generally makes diagnosing failures somewhat more difficult. + +Once a dialer has started, it is generally not possible to change +it's configuration. + +== RETURN VALUES + +This function returns 0 on success, and non-zero otherwise. + +== ERRORS + +`NNG_EADDRINVAL`:: An invalid _url_ was specified. +`NNG_ECLOSED`:: The socket _s_ is not open. +`NNG_ECONNREFUSED`:: The remote peer refused the connection. +`NNG_ECONNRESET`:: The remote peer reset the connection. +`NNG_EINVAL`:: An invalid set of _flags_ was specified. +`NNG_ENOMEM`:: Insufficient memory is available. +`NNG_EPEERAUTH`:: Authentication or authorization failure. +`NNG_EPROTO`:: A protocol error occurred. +`NNG_ESTATE`:: The dialer _d_ is already started. +`NNG_EUNREACHABLE`:: The remote address is not reachable. + +== SEE ALSO + +<<nng_dial#,nng_dial(3)>>, +<<nng_dialer_create#,nng_dialer_create(3)>> +<<nng_strerror#,nng_strerror(3)>>, +<<nng#,nng(7)>> + +== COPYRIGHT + +{copyright}
