OutputStream.writeBytesAsync

This function is similar to gio.output_stream.OutputStream.writeAsync, but takes a #GBytes as input. Due to the refcounted nature of #GBytes, this allows the stream to avoid taking a copy of the data.

However, note that this function may still perform partial writes, just like gio.output_stream.OutputStream.writeAsync. If that occurs, to continue writing, you will need to create a new #GBytes containing just the remaining bytes, using glib.bytes.Bytes.newFromBytes. Passing the same #GBytes instance multiple times potentially can result in duplicated data in the output stream.

For the synchronous, blocking version of this function, see gio.output_stream.OutputStream.writeBytes.

Parameters

bytes glib.bytes.Bytes

The bytes to write

ioPriority int

the io priority of the request.

cancellable gio.cancellable.Cancellable

optional #GCancellable object, null to ignore.

callback gio.types.AsyncReadyCallback

a #GAsyncReadyCallback to call when the request is satisfied
