Gio.MemoryOutputStream

const Gio = imports.gi.Gio;

let memoryOutputStream = new Gio.MemoryOutputStream({
    data: value,
    destroy_function: value,
    realloc_function: value,
    size: value,
});
  

Gio.MemoryOutputStream is a class for using arbitrary memory chunks as output for GIO streaming output operations.

As of GLib 2.34, Gio.MemoryOutputStream trivially implements Gio.PollableOutputStream: it always polls as ready.
