buf.readBigInt64LE([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 读取有符号的小端序 64 位整数。

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

从 Buffer 读取的整数被解释为二进制补码有符号值。
