[local]
HRESULT CopyContentToFileAtOffset(
  [in] PFIO_CONTEXT pFIOCopy,
  [in] DWORD dwOffset,
  [in,unique] IMailMsgNotify *pNotify
);

pFIOCopy: Specifies the previously opened file into which to copy the contents. The file handle within the FIO_CONTEXT must have been opened with the FILE_FLAG_OVERLAPPED flag and associated with the FIO_CONTEXT structure using the AssociateFile function.
dwOffset: The offset within the file into which to copy the message contents.
pNotify: Callback interface used to asynchronously notify you that the method has completion. If this value is NULL, then the operation will complete synchronously. Even if this value is non-NULL, the operation may still complete synchronously. In this case, the method returns S_OK instead of MAILMSG_S_PENDING.

Value	Description
S_OK	Success. The operation completed synchronously.
MAILMSG_S_PENDING	Success. The operation will complete asynchronously. When it completes, you will be notified through the interface you passed using the pNotify parameter. The result of the operation will be returned with the notification callback method.
