buf.readUInt16LE([offset])


    从指定的 offset 处的 buf 读取无符号的小端序 16 位整数。

    • offset <integer> Number of bytes to skip before starting to read. Must satisfy 0 <= offset <= buf.length - 2. Default: 0.
    • Returns: <integer>

    Reads an unsigned, little-endian 16-bit integer from buf at the specified offset.

    This function is also available under the readUint16LE alias.

    const buf = Buffer.from([0x12, 0x34, 0x56]);
    
    console.log(buf.readUInt16LE(0).toString(16));
    // Prints: 3412
    console.log(buf.readUInt16LE(1).toString(16));
    // Prints: 5634
    console.log(buf.readUInt16LE(2).toString(16));
    // Throws ERR_OUT_OF_RANGE.
