writeBytes
open fun writeBytes(bytes: <Error class: unknown class>, cancellable: Cancellable? = null): <Error class: unknown class><Long>
A wrapper function for g_output_stream_write() which takes a #GBytes as input. This can be more convenient for use by language bindings or in other cases where the refcounted nature of #GBytes is helpful over a bare pointer interface.
However, note that this function may still perform partial writes, just like g_output_stream_write(). If that occurs, to continue writing, you will need to create a new #GBytes containing just the remaining bytes, using g_bytes_new_from_bytes(). Passing the same #GBytes instance multiple times potentially can result in duplicated data in the output stream.
Return
Number of bytes written, or -1 on error
Parameters
bytes
the #GBytes to write
cancellable
optional cancellable object
