writeBigInt64LE

fun writeBigInt64LE(value: BigInt, offset: Number = definedExternally): Double(source)

Writes value to buf at the specified offset as little-endian.

value is interpreted and written as a two's complement signed integer.

import { Buffer } from 'node:buffer';

const buf = Buffer.allocUnsafe(8);

buf.writeBigInt64LE(0x0102030405060708n, 0);

console.log(buf);
// Prints: <Buffer 08 07 06 05 04 03 02 01>

Since

v12.0.0, v10.20.0

Return

offset plus the number of bytes written.

Parameters

value

Number to be written to buf.

offset=0 Number of bytes to skip before starting to write. Must satisfy: 0 <= offset <= buf.length - 8.
