- Description
The ReceiveLobbyMessage method will retrieve messages sent between lobby client and application.
Error values that can be generated are:
DPERR_APPNOTSTARTED
DPERR_BUFFERTOOSMALL
DPERR_GENERIC
DPERR_INVALIDINTERFACE
DPERR_INVALIDOBJECT
DPERR_INVALIDPARAMS
DPERR_NOMESSAGES
DPERR_OUTOFMEMORY
- Parameters
AppID
The AppID parameter identifies which applications messages to retrieve.
Only valid when the method is being called by a lobby client.
Set zero when calling from an application.
MessageFlags
The MessageFlags parameter defines flags indicating the type of message being retrieved.
The described effect applies when the flag is set.
The default setting of zero indicates a custom message defined by the sender.
-
DPLMSG_STANDARD
The message is a standard DirectPlay defined message.
Processing of the message is optional.
DPLMSG_SYSTEM
The message was generated by the system to inform the lobby of application status changes.
The Data parameter will reference the retrieved message if the method returns successfully.
Set NULL to retrieve the required buffer size in the DataSize parameter.
DataSize
The DataSize parameter references the size, in bytes, of the Data buffer.
Before the call, set this to the size of the Data buffer.
After the call, it will indicate how many bytes were written to the Data buffer.
If the Data buffer was too small, this parameter will be set to the required size and DPERR_BUFFERTOOSMALL returned.
