method

buffer.Buffer.writeIntBE

value: number,

offset: number,

byteLength: number

): number;

Writes byteLength bytes of value to buf at the specified offsetas big-endian. Supports up to 48 bits of accuracy. Behavior is undefined whenvalue is anything other than a signed integer.

import { Buffer } from 'node:buffer';

const buf = Buffer.allocUnsafe(6);

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

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

@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.
