    void set_OnTransferDataNeeded(TSBReceiveEvent pMethodValue, void * pDataValue);
    typedef void (SB_CALLBACK *TSBReceiveEvent)(void * _ObjectData, TObjectHandle Sender, void * Buffer, int32_t MaxSize, int32_t &Written);

[PHP]
    TSBReceiveEvent|callable|NULL get_OnTransferDataNeeded()
    void set_OnTransferDataNeeded(TSBReceiveEvent|callable|NULL $Value)
    callable TSBReceiveEvent(TObject $Sender, TSBPointer|NULL $Buffer, integer $MaxSize, integer &$Written)

Parameters

  • Buffer - the buffer that should be filled with data.
