/**
|
|
* Write `buffer` to the file specified by `fd`. If `buffer` is a normal object, it
|
|
* must have an own `toString` function property.
|
|
*
|
|
* `offset` determines the part of the buffer to be written, and `length` is
|
|
* an integer specifying the number of bytes to write.
|
|
*
|
|
* `position` refers to 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. See [`pwrite(2)`](http://man7.org/linux/man-pages/man2/pwrite.2.html).
|
|
*
|
|
* The callback will be given three arguments `(err, bytesWritten, buffer)` where`bytesWritten` specifies how many _bytes_ were written from `buffer`.
|
|
*
|
|
* If this method is invoked as its `util.promisify()` ed version, it returns
|
|
* a promise for an `Object` with `bytesWritten` and `buffer` properties.
|
|
*
|
|
* It is unsafe to use `fs.write()` multiple times on the same file without waiting
|
|
* for the callback. For this scenario, {@link createWriteStream} is
|
|
* recommended.
|
|
*
|
|
* 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 v0.0.2
