IDirectPlay3::GetPlayerData

IDirectPlay3 Interface

Retrieves an application-specific data block that was associated with a player ID by using IDirectPlay3::SetPlayerData.

HRESULT GetPlayerData(
  DPID idPlayer,
  LPVOID lpData,
  LPDWORD lpdwDataSize,
  DWORD dwFlags
  );

Parameters

idPlayer

ID of the player for which data is being requested.

lpData

Pointer to a buffer where the application-specific player data is to be written. Set this parameter to NULL to request only the size of data. The lpdwDataSize parameter will be set to the size required to hold the data.

lpdwDataSize

Pointer to a variable that is initialized to the size of the buffer before calling this method. After the method returns, this parameter will be set to the size, in bytes, of the group data. If the buffer was too small (DPERR_BUFFERTOOSMALL), then this parameter will be set to the buffer size required.

dwFlags

If this parameter is set to 0, the remote data will be retrieved.

DPGET_LOCAL

Retrieves the local data set by this application.

DPGET_REMOTE

Retrieves the current data from the remote shared data space.

Return Values

Returns DP_OK if successful, or one of the following error values otherwise:

DPERR_BUFFERTOOSMALL

DPERR_INVALIDFLAGS

DPERR_INVALIDOBJECT

DPERR_INVALIDPLAYER

Remarks

DirectPlay can maintain two types of player data: local and remote. The application must specify which type of data to retrieve. Local data was set by this DirectPlay object by using the DPSET_LOCAL flag. Remote data might have been set by any application in the session by using the DPSET_REMOTE flag.
