buf.writeBigUInt64BE(value[, offset])
-
value
<bigint> 要写入buf
的数字。¥
value
<bigint> Number to be written tobuf
. -
offset
<integer> 开始写入之前要跳过的字节数。必须满足:0 <= offset <= buf.length - 8
。默认值:0
。¥
offset
<integer> Number of bytes to skip before starting to write. Must satisfy:0 <= offset <= buf.length - 8
. Default:0
. -
返回:<integer>
offset
加上写入的字节数。¥Returns: <integer>
offset
plus the number of bytes written.
将 value
作为大端序写入 buf
中指定的 offset
。
¥Writes value
to buf
at the specified offset
as big-endian.
此函数也可在 writeBigUint64BE
别名下使用。
¥This function is also available under the writeBigUint64BE
alias.
import { Buffer } from 'node:buffer';
const buf = Buffer.allocUnsafe(8);
buf.writeBigUInt64BE(0xdecafafecacefaden, 0);
console.log(buf);
// Prints: <Buffer de ca fa fe ca ce fa de>
const { Buffer } = require('node:buffer');
const buf = Buffer.allocUnsafe(8);
buf.writeBigUInt64BE(0xdecafafecacefaden, 0);
console.log(buf);
// Prints: <Buffer de ca fa fe ca ce fa de>
