buf.readUInt32LE([offset])

• offset <integer> 开始读取之前要跳过的字节数。必须满足 0 <= offset <= buf.length - 4。默认值:0。

  \offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 4. Default: 0.

• 返回:<integer>

  \Returns: <integer>

从指定的 offset 处的 buf 读取无符号的小端序 32 位整数。

\Reads an unsigned, little-endian 32-bit integer from buf at the specified offset.

此函数也可在 readUint32LE 别名下使用。

\This function is also available under the readUint32LE alias.

import { Buffer } from 'node:buffer';

console.log(buf.readUInt32LE(0).toString(16));
// Prints: 78563412
