Example

// The following example shows how to use the FleetProvisioning_MatchTopic
// function to check if an incoming MQTT publish message is a Fleet
// Provisioning message.
 
FleetProvisioningTopic_t api;
FleetProvisioningStatus_t status = FleetProvisioningError;
 
// pTopic and topicLength are the topic string and length of the topic on
// which the publish message is received. These are usually provided by the
// MQTT library used.
status = FleetProvisioning_MatchTopic( pTopic
                                       topicLength,
                                       &( api ) );
 
if( status == FleetProvisioningSuccess )
{
     if( api == FleetProvJsonCreateCertFromCsrAccepted )
     {
         // The published JSON request was accepted and completed by the AWS
         // IoT Fleet Provisioning service. You can parse the response using
         // your choice of JSON parser get the certificate, ID, and ownership
         // token.
     }
     else if( api == FleetProvJsonCreateCertFromCsrRejected )
     {
         // The published JSON request was rejected by the AWS IoT Fleet
         // Provisioning service.
     }
     else
     {
         // Unexpected response.
     }
