/**
|
|
* Write an array of `ArrayBufferView`s to the file specified by `fd` using`writev()`.
|
|
*
|
|
* `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`, and`buffers`. `bytesWritten` is how many bytes were written from `buffers`.
|
|
*
|
|
* If this method is `util.promisify()` ed, it returns a promise for an`Object` 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 {@link 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.

|
* @since v12.9.0
