An application-defined callback function used with ReadEncryptedFileRaw.
The system calls ExportCallback one or more times, each time with a block
of the encrypted file's data, until it has received all of the file data.
ExportCallback writes the encrypted file's data to another storage media,
usually for purposes of backing up the file.
