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
。
- 返回: <bigint>
从指定的 offset
处的 buf
读取有符号的大端序 64 位整数。
从 Buffer
读取的整数被解释为二进制补码有符号值。

offset
<integer> Number of bytes to skip before starting to read. Must
satisfy: 0 <= offset <= buf.length - 8
. Default: 0
.
- Returns: <bigint>
Reads a signed, big-endian 64-bit integer from buf
at the specified offset
.
Integers read from a Buffer
are interpreted as two's complement signed
values.
