buffer.Buffer.writeUIntLE

writeUIntLE(

value: number,

offset: number,

byteLength: number

): number;

Writes byteLength bytes of value to buf at the specified offsetas little-endian. Supports up to 48 bits of accuracy. Behavior is undefined when value is anything other than an unsigned integer.

This function is also available under the writeUintLE alias.

import { Buffer } from 'node:buffer';

const buf = Buffer.allocUnsafe(6);

buf.writeUIntLE(0x1234567890ab, 0, 6);

console.log(buf);
// Prints: <Buffer ab 90 78 56 34 12>

@param value

Number to be written to buf.

@param offset

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

@param byteLength

Number of bytes to write. Must satisfy 0 < byteLength <= 6.

@returns

offset plus the number of bytes written.
