filehandle.readv(buffers[, position])

• buffers <Buffer[]> | <TypedArray[]> | <DataView[]>
• position <integer> | <null> 要从中读取数据的文件的开头偏移量。 如果 position 不是 number，则将从当前位置读取数据。 默认值: null
• 返回: <Promise> 成功时将使用包含以下两个属性的对象履行：
  • bytesRead <integer> 读取的字节数
  • buffers <Buffer[]> | <TypedArray[]> | <DataView[]> 该属性包含对 buffers 输入的引用。

从文件读取并写入 <ArrayBufferView> 的数组

• buffers <Buffer[]> | <TypedArray[]> | <DataView[]>
• position <integer> | <null> The offset from the beginning of the file where the data should be read from. If position is not a number, the data will be read from the current position. Default: null
• Returns: <Promise> Fulfills upon success an object containing two properties:
  • bytesRead <integer> the number of bytes read
  • buffers <Buffer[]> | <TypedArray[]> | <DataView[]> property containing a reference to the buffers input.

Read from a file and write to an array of <ArrayBufferView>s
