fdatasync method

Future<void> fdatasync(
  1. num rid
)

Flushes any pending data operations of the given file stream to disk.

const file = await Deno.open(
 "my_file.txt",
 { read: true, write: true, create: true },
);
await Deno.write(file.rid, new TextEncoder().encode("Hello World"));
await Deno.fdatasync(file.rid);
console.log(new TextDecoder().decode(await Deno.readFile("my_file.txt"))); // Hello World

Implementation

_i2.Future<void> fdatasync(_i2.num rid) => _i3.promiseToFuture(_i3.callMethod(
      this,
      'fdatasync',
      [rid],
    ));
