char *app_name,
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 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 Broker client. See Client Identifiers for more information.
client_group
The name of the client group for the Broker client. Client groups are discussed in Administering webMethods Broker.
app_name
The name of the application that will contain the Broker client.
desc
The connection descriptor to use for the 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 Broker client. This parameter is used for output.
Attempts to create a new transactional Broker client with an event queue and zero subscriptions. If a Broker client with the same client_id already exists, this client will be reconnected. After invoking this function, the Broker client may begin processing events.
The client state sharing property of desc will be ignored if the Broker client already exists and is being reconnected.
The application is responsible for invoking either the awDisconnectClient or awDestroyClient function when the Broker client is no longer needed.
