This method requests up-to-date data for group messages from the MSN Direct receiver.
Syntax
int GetGroupMessages();
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 GetGroupMessages method uses RequestSync to perform the transaction, with GROUP_MESSAGE specified in the applicationType parameter.
The group messages are returned asynchronously in the messageFromReceiver parameter of the ProcessInMessageFromReceiver call. The GroupMessageMsg 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.
