dataview.getBigUint64(byteOffset [, littleEndian])
- The offset, in bytes, from the start of the view to read the data from.
- Optional Indicates whether the 64-bit int is stored in little- or big-endian format. If
undefined, a big-endian value is read.
- Thrown if the
byteOffsetis set such that it would read beyond the end of the view.
There is no alignment constraint; multi-byte values may be fetched from any offset.
