buf.readUInt16LE([offset])
从指定的 offset
处的 buf
读取无符号的小端序 16 位整数。
此函数也可在 readUint16LE
别名下使用。
const buf = Buffer.from([0x12, 0x34, 0x56]);
console.log(buf.readUInt16LE(0).toString(16));
// 打印: 3412
console.log(buf.readUInt16LE(1).toString(16));
// 打印: 5634
console.log(buf.readUInt16LE(2).toString(16));
// 抛出 ERR_OUT_OF_RANGE。
offset
<integer> Number of bytes to skip before starting to read. Must satisfy0 <= 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.
