Syntax Elements

object
the object.
ctxid
a context identifier.
start
the starting byte offset, relative to 0, for the read operation. If this value is greater than or equal to the length of the object, then the resulting data stream will have a zero length.
maxlength
the maximum number of bytes to read. If this value is 0, or if start + maxlength is greater than the object length, then the read operation terminates when the length of the object is exhausted.
