filehandle.readv(buffers[, position])

从文件读取并写入 ArrayBufferView 的数组

如果 typeof position !== 'number',则从当前位置读取数据。

Read from a file and write to an array of ArrayBufferViews

The Promise is resolved with an object containing a bytesRead property identifying the number of bytes read, and a buffers property containing a reference to the buffers input.

position is the offset from the beginning of the file where this data should be read from. If typeof position !== 'number', the data will be read from the current position.
