ListTopicSubscriptions Method
Lists subscriptions to the specified topic.
Syntax
sns.listTopicSubscriptions(topicArn, [callback])
Callback
The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).
The callback for this method is defined as:
function(err){ }
'err' is the error that occurred. If there was no error, then 'err' is 'null'.
'err' has 2 properties which hold detailed information:
err.code err.message
Remarks
This method lists the subscriptions to the specified topic.
When calling this method the subscriptions to the topic specified by TopicARN will be listed. The SubscriptionList event will fire once for each subscription and the Subscription* properties will be populated with information about the subscriptions.
If more than 100 subscriptions exist the results will be paged. The IsSubscriptionPaged setting will return the value "True" and SubscriptionMarker will be populated. You may continue to call this method until IsSubscriptionPaged returns "False" and SubscriptionMarker is empty to retrieve all results.
