Add a Bytes record with the given names.
Parameters | bytes | The bytes to insert. |
| names | The names to give the inserted bytes. Each name is
a tuple of bytestrings. The bytestrings may not contain
whitespace. |
Returns | An offset, length tuple. The offset is the offset
of the record within the container, and the length is the
length of data that will need to be read to reconstitute the
record. These offset and length can only be used with the pack
interface - they might be offset by headers or other such details
and thus are only suitable for use by a ContainerReader. |
