buf.readUIntLE(offset, byteLength)

• offset <integer> 开始读取之前要跳过的字节数。必须满足 0 <= offset <= buf.length - byteLength。

  ¥offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - byteLength.

• byteLength <integer> 要读取的字节数。必须满足 0 < byteLength <= 6。

  ¥byteLength <integer> Number of bytes to read. Must satisfy 0 < byteLength <= 6.

• 返回：<integer>

  ¥Returns: <integer>

从指定的 offset 处的 buf 读取 byteLength 个字节，并将结果解释为支持最高 48 位精度的无符号小端序整数。

¥Reads byteLength number of bytes from buf at the specified offset and interprets the result as an unsigned, little-endian integer supporting up to 48 bits of accuracy.

此函数也可在 readUintLE 别名下使用。

¥This function is also available under the readUintLE alias.

import { Buffer } from 'node:buffer';

const buf = Buffer.from([0x12, 0x34, 0x56, 0x78, 0x90, 0xab]);

console.log(buf.readUIntLE(0, 6).toString(16));
// Prints: ab9078563412const { Buffer } = require('node:buffer');

const buf = Buffer.from([0x12, 0x34, 0x56, 0x78, 0x90, 0xab]);

console.log(buf.readUIntLE(0, 6).toString(16));
// Prints: ab9078563412拷贝
