EnablePublishConfirms Method

Enables publish confirmations mode for a channel.

Syntax

int EnablePublishConfirms(const QString& qsChannelName, bool bNoWait);

Remarks

This method enables publish confirmations mode for the channel with the given ChannelName.

While a channel is in publish confirmations mode, the server will acknowledge each message published by the class. The class will wait to fire the MessageOut event until it receives this acknowledgement. (Note that this mode is only available when the RabbitMQCompatible configuration setting is enabled.)

Note that a channel will stay in publish confirmations mode, once enabled, until it is deleted.

The NoWait parameter, if True, will cause the server to execute the request asynchronously. For asynchronous request handling, the server only sends back a response in case of an error.

An exception is thrown if the RabbitMQCompatible configuration setting is currently False, if no channel with the given ChannelName exists, or if EnableTransactionMode has been called for the specified channel previously.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
