mosquitto 所有错误代码

mosquitto 版本为mosquitto version 1.6.9,错误代码如下

/* Error values */
enum mosq_err_t {
    MOSQ_ERR_AUTH_CONTINUE = -4,
    MOSQ_ERR_NO_SUBSCRIBERS = -3,
    MOSQ_ERR_SUB_EXISTS = -2,
    MOSQ_ERR_CONN_PENDING = -1,
    MOSQ_ERR_SUCCESS = 0,
    MOSQ_ERR_NOMEM = 1,
    MOSQ_ERR_PROTOCOL = 2,
    MOSQ_ERR_INVAL = 3,
    MOSQ_ERR_NO_CONN = 4,
    MOSQ_ERR_CONN_REFUSED = 5,
    MOSQ_ERR_NOT_FOUND = 6,
    MOSQ_ERR_CONN_LOST = 7,
    MOSQ_ERR_TLS = 8,
    MOSQ_ERR_PAYLOAD_SIZE = 9,
    MOSQ_ERR_NOT_SUPPORTED = 10,
    MOSQ_ERR_AUTH = 11,
    MOSQ_ERR_ACL_DENIED = 12,
    MOSQ_ERR_UNKNOWN = 13,
    MOSQ_ERR_ERRNO = 14,
    MOSQ_ERR_EAI = 15,
    MOSQ_ERR_PROXY = 16,
    MOSQ_ERR_PLUGIN_DEFER = 17,
    MOSQ_ERR_MALFORMED_UTF8 = 18,
    MOSQ_ERR_KEEPALIVE = 19,
    MOSQ_ERR_LOOKUP = 20,
    MOSQ_ERR_MALFORMED_PACKET = 21,
    MOSQ_ERR_DUPLICATE_PROPERTY = 22,
    MOSQ_ERR_TLS_HANDSHAKE = 23,
    MOSQ_ERR_QOS_NOT_SUPPORTED = 24,
    MOSQ_ERR_OVERSIZE_PACKET = 25,
    MOSQ_ERR_OCSP = 26,
    MOSQ_ERR_TIMEOUT = 27,
    MOSQ_ERR_RETAIN_NOT_SUPPORTED = 28,
    MOSQ_ERR_TOPIC_ALIAS_INVALID = 29,
    MOSQ_ERR_ADMINISTRATIVE_ACTION = 30,
    MOSQ_ERR_ALREADY_EXISTS = 31,
};

在运行程序时候，得到mosquitto_connect ret = 14　
经过诊断，应该是网络不通。。。
