g_output_stream_write_bytes (
  GOutputStream* stream,
  GBytes* bytes,
  GCancellable* cancellable,
  GError** error


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.



Type: GBytes

The GBytes to write.

The data is owned by the caller of the function.

Type: GCancellable

Optional cancellable object.

The argument can be NULL.
The data is owned by the caller of the function.

Type: GError **

The return location for an error.

The argument can be NULL.
The argument will be set to NULL by the function if there are no errors.
In case of error, the argument will be set and the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: gssize

Number of bytes written, or -1 on error.
