readv
external fun readv(fd: Number, buffers: ReadonlyArray<ArrayBufferView>, cb: (err: ErrnoException?, bytesRead: Double, ReadonlyArray<ArrayBufferView>) -> Unit)(source)
Read from a file specified by fd
and write to an array of ArrayBufferView
s using readv()
.
position
is the offset from the beginning of the file from where data should be read. If typeof position !== 'number'
, the data will be read from the current position.
The callback will be given three arguments: err
, bytesRead
, and buffers
. bytesRead
is how many bytes were read from the file.
If this method is invoked as its util.promisify()
ed version, it returns a promise for an Object
with bytesRead
and buffers
properties.
