LongLongWord *Size);
[C++ (VCL)]
typedef void (__closure *TCBDiskGetFileSizeEvent)(
System::TObject* Sender,

Parameters
- Sender - reference to the class that called the delegate/event handler.
- Size - out parameter where the application must place the size of the file.
- Result - out parameter (return value for DLL) where the application places the result of the operation. If you are working with file system, Win32 error code is a good candidate for placing to Result parameter. Otherwise you can use any other error codes, just be sure that 0 means success.
