buf.readBigUInt64LE([offset])

• offset <integer> 开始读取之前要跳过的字节数。必须满足:0 <= offset <= buf.length - 8。默认值:0。

  \offset <integer> Number of bytes to skip before starting to read. Must satisfy: 0 <= offset <= buf.length - 8. Default: 0.

• 返回:<bigint>

  \Returns: <bigint>

从指定的 offset 处的 buf 读取无符号的小端序 64 位整数。

\Reads an unsigned, little-endian 64-bit integer from buf at the specified offset.

此函数也可在 readBigUint64LE 别名下使用。

\This function is also available under the readBigUint64LE alias.
