import { writev } from "https://deno.land/std@0.145.0/node/fs.ts";
Write an array of ArrayBufferView
s to the file specified by fd
usingwritev()
.
position
is the offset from the beginning of the file where this data
should be written. If typeof position !== 'number'
, the data will be written
at the current position.
The callback will be given three arguments: err
, bytesWritten
, andbuffers
. bytesWritten
is how many bytes were written from buffers
.
If this method is util.promisify()
ed, it returns a promise for anObject
with bytesWritten
and buffers
properties.
It is unsafe to use fs.writev()
multiple times on the same file without
waiting for the callback. For this scenario, use createWriteStream.
On Linux, positional writes don't work when the file is opened in append mode. The kernel ignores the position argument and always appends the data to the end of the file.
