import { write } from "https://deno.land/std@0.145.0/node/fs.ts";
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)
.
The callback will be given three arguments (err, bytesWritten, buffer)
wherebytesWritten
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 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.
Asynchronously writes buffer
to the file referenced by the supplied file descriptor.
Parameters
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
.
Asynchronously writes buffer
to the file referenced by the supplied file descriptor.
Asynchronously writes buffer
to the file referenced by the supplied file descriptor.
Asynchronously writes string
to the file referenced by the supplied file descriptor.
Parameters
The offset from the beginning of the file where this data should be written. If not supplied, defaults to the current position.
Asynchronously writes string
to the file referenced by the supplied file descriptor.
Parameters
The offset from the beginning of the file where this data should be written. If not supplied, defaults to the current position.
