Gio.pollable_stream_write_all

function pollable_stream_write_all(stream: Gio.OutputStream, buffer: ByteArray, blocking: Boolean, cancellable: Gio.Cancellable): [ok: Boolean, bytes_written: Number(gsize)] {
    // Gjs wrapper for g_pollable_stream_write_all()
}
  

Tries to write count bytes to stream, as with Gio.OutputStream.prototype.write_all, but using Gio.pollable_stream_write rather than Gio.OutputStream.prototype.write.

On a successful write of count bytes, true is returned, and bytes_written is set to count.

If there is an error during the operation (including Gio.IOErrorEnum.would_block in the non-blocking case), false is returned and @error is set to indicate the error status, bytes_written is updated to contain the number of bytes written into the stream before the error occurred.

As with Gio.pollable_stream_write, if blocking is false, then stream must be a Gio.PollableOutputStream for which Gio.PollableOutputStream.prototype.can_poll returns true or else the behavior is undefined. If blocking is true, then stream does not need to be a Gio.PollableOutputStream.
