buf.readUInt32LE([offset])
从指定的 offset
处的 buf
读取无符号的小端序 32 位整数。
此函数也可在 readUint32LE
别名下使用。
const buf = Buffer.from([0x12, 0x34, 0x56, 0x78]);
console.log(buf.readUInt32LE(0).toString(16));
// 打印: 78563412
console.log(buf.readUInt32LE(1).toString(16));
// 抛出 ERR_OUT_OF_RANGE。
offset
<integer> Number of bytes to skip before starting to read. Must satisfy0 <= offset <= buf.length - 4
. Default:0
.- Returns: <integer>
Reads an unsigned, little-endian 32-bit integer from buf
at the specified
offset
.
This function is also available under the readUint32LE
alias.
const buf = Buffer.from([0x12, 0x34, 0x56, 0x78]);
console.log(buf.readUInt32LE(0).toString(16));
// Prints: 78563412
console.log(buf.readUInt32LE(1).toString(16));
// Throws ERR_OUT_OF_RANGE.
