DPLMSG_GETPROPERTYRESPONSE

Message sent by a lobby to an application in response to a DPLMSG_GETPROPERTY message. The request that is being filled is identified by the dwRequestID parameter.

typedef struct {

DWORD dwType;

DWORD dwRequestID

GUID guidPlayer;

GUID guidPropertyTag;

HRESULT hr;

DWORD dwDataSize;

DWORD dwPropertyData[1];

} DPLMSG_GETPROPERTYRESPONSE, FAR *LPDPLMSG_GETPROPERTYRESPONSE;

Members

dwType

Identifies the message. This value is DPSYS_ GETPROPERTYRESPONSE.

dwRequestID

The ID that identifies the DPLMSG_GETPROPERTY message that this message is in response to.

guidPlayer

GUID identifying the player that this property applies to (if applicable). If the property is not player-specific, this member will be set to GUID_NULL. This will be the same as the GUID from the DPLMSG_GETPROPERTY message.

guidPropertyTag

A GUID identifying the property that is being requested. This will be the same as the GUID from the DPLMSG_GETPROPERTY message.

hr

Return code for the get property request. One of the following values:

DP_OK - successfully returned the property.

DPERR_UNKNOWN - the requested property is unknown to the lobby.

DPERR_UNAVAILABLE - the requested property is unavailable.

dwDataSize

The size, in bytes, of the property data.

dwPropertyData

A variable-size buffer that contains the property data. The property tag will define how to interpret this data.

Remarks

A lobby must either respond to all DPLMSG_GETPROPERTY requests or none of them.

When constructing this message, the lobby needs to allocate enough memory to hold the DPLMSG_GETPROPERTYRESPONSE structure and the complete property data. For example, if the property data requires 52 bytes, the lobby will allocate (sizeof(DPLMSG_GETPROPERTYRESPONSE) + 52) bytes and assign it to a DPLMSG_GETPROPERTYRESPONSE pointer.
