BrokerError awReconnectBrokerTxClient(
char *broker_host,
char *broker_name,
char *client_id,
BrokerConnectionDescriptor desc,
BrokerTxClient *txclient);
broker_host
The name of the host which is running the Broker that the Transactional Broker client will use. Specified in the form <broker_host_name>:<port_number>. If you omit the port number, the default port number will be used. For example: MyHost:12000
broker_name
The name of the Broker to which the Transactional Broker client will be connected. If NULL, the default Broker will be used. If specified, the length of this parameter must be 1 to 255 ANSI characters or 1 to 42 Unicode characters.
client_id
A string containing a unique identifier for creating or reconnecting the Transactional Broker client. See Client Identifiers for more information. The client id can be NULL to request the Broker to create an identifier (usually used with destroy-on-disconnect clients).
desc
The connection descriptor to use for the Transactional Broker client. If NULL, a default connection will be established for the new client, which may be shared with other Broker clients.
txclient
A pointer to the reconnected or newly created Transactional Broker client. This parameter is used for output.
Reconnects a transactional client. broker_name can be NULL to request the default Broker. desc can be NULL to request a default connection. The state sharing flag in the descriptor is ignored by this call. Whether or not the client shares state can only be set when making a new transactional client. For normal clients, only one active connection can be made to the Broker for a given client_id, so an error can be returned on reconnect if the client_id is already in use. For clients with shared state, multiple reconnects to the client_id can be made, but an error can be returned if the share limit is exceeded.
The caller is responsible for calling awDestroyClient on the output value.
