This method requests up-to-date data about Common Alerting Protocol (CAP) emergency supplemental alerts from the MSN Direct receiver.
Syntax
int GetCapEmergencyAlertsSuppl();
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 GetCapEmergencyAlertsSuppl method uses RequestSync to perform the transaction, with CAP_EMERGENCY_ALERTS_SUPPL specified in the applicationType parameter.
The Common Alerting Protocol (CAP) supplemental alerts are returned asynchronously in the messageFromReceiver parameter in the ProcessInMessageFromReceiver call. The CapEmergencyAlertsSupplMsg 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.
