- uproot.deserialization.numbytes_version(chunk, cursor, context, move=True)
- Parameters:
- chunk (uproot.source.chunk.Chunk) – Buffer of contiguous data from the file uproot.source.chunk.Source. 
- cursor (uproot.Cursor) – Current position in that - chunk.
- context (dict) – Auxiliary data used in deserialization. 
- move (bool) – If True, move the - cursorto a position just past the bytes that were read. If False, don’t move the- cursorat all.
 
 - Deserialize a number of bytes and version number, which is usually 6 bytes but may be 2 bytes if the number of bytes isn’t given. - Returns a 3-tuple of - number of bytes (int or None if unknown) 
- instance version (int) 
- is memberwise (bool): True if the memberwise bit is set in the version number; False otherwise.
