function write
Usage in Deno
```typescript import { write } from "node:node__fs.d.ts"; ```
write<TBuffer extends ArrayBufferView>(fd: number,buffer: TBuffer,offset: number
| undefined
| null,length: number
| undefined
| null,position: number
| undefined
| null,callback: (err: ErrnoException | null,written: number,buffer: TBuffer,) => void,): void
Write `buffer` to the file specified by `fd`.
`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, [createWriteStream](../.././node__fs.d.ts/~/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.

write<TBuffer extends ArrayBufferView>(fd: number,buffer: TBuffer,offset: number
| undefined
| null,length: number
| undefined
| null,callback: (err: ErrnoException | null,written: number,buffer: TBuffer,) => void,): void
Asynchronously writes `buffer` to the file referenced by the supplied file descriptor.
buffer: TBuffer
The part of the buffer to be written. If not supplied, defaults to `0`.
The number of bytes to write. If not supplied, defaults to `buffer.length - offset`.
void
write<TBuffer extends ArrayBufferView>(fd: number,buffer: TBuffer,offset: number
| undefined
| null,callback: (err: ErrnoException | null,written: number,buffer: TBuffer,) => void,): void
Asynchronously writes `buffer` to the file referenced by the supplied file descriptor.

| undefined
| null,callback: (err: ErrnoException | null,written: number,str: string,) => void,): void
Asynchronously writes `string` to the file referenced by the supplied file descriptor.
The offset from the beginning of the file where this data should be written. If not supplied, defaults to the current position.
