Description
Writes a filer signature to the writer object's associated stream.
WriteSignature is used internally by several methods that write the filer signature before processing some action. For example, the WriteRootComponent method calls WriteSignature before writing its component to the stream. By checking for the signature before loading objects, reader objects can guard against inadvertently reading invalid or corrupted data.
