This method requests up-to-date data about traffic incidents from the MSN Direct receiver. Traffic-incidents data includes warnings about events that block traffic flow, such as accidents, road closures, and road construction in the local area.
Note
Traffic-incidents data is available in most states/regions in North America.
Syntax
int GetTrafficIncidents();
Parameters
None.
Return Value
Returns the transaction ID of the request that is sent to the MSN Direct receiver; returns -1 if the request fails.
Remarks
The GetTrafficIncidents method uses RequestSync to perform the transaction, with TRAFFIC_INCIDENTS specified in the applicationType parameter.
The traffic-incidents messages are returned asynchronously in the messageFromReceiver parameter of the ProcessInMessageFromReceiver call. The TrafficIncidentsMsg object in the sample application illustrates how to parse this type of message.
Warning
The functions in the sample message classes handle data that arrives in a specific format in the payload of an incoming message. If you modify the way in which data is extracted from incoming messages, the message classes will not work as expected.
