method Buffer.writeBigInt64BE

Usage in Deno

```typescript import { type Buffer } from "node:node__buffer.d.ts"; ```



Buffer.writeBigInt64BE(value: bigint,
offset?: number,
): number

Writes `value` to `buf` at the specified `offset` as big-endian. `value` is interpreted and written as a two's complement signed integer. ```js import { Buffer } from 'node:buffer'; const buf = Buffer.allocUnsafe(8); buf.writeBigInt64BE(0x0102030405060708n, 0); console.log(buf); // Prints: ```

Parameters



value: bigint

Number to be written to `buf`.

optional



offset: number = 0

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

Return Type

number
