g_output_stream_write_all_async (
  GOutputStream* stream,
  void* buffer,
  gsize count,
  int io_priority,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data


Request an asynchronous write of count bytes from buffer into the stream. When the operation is finished callback will be called. You can then call g_output_stream_write_all_finish() to get the result of the operation.

This is the asynchronous version of g_output_stream_write_all().

Call g_output_stream_write_all_finish() to collect the result.

Any outstanding I/O request with higher priority (lower numerical value) will be executed before an outstanding request with lower priority. Default priority is G_PRIORITY_DEFAULT.

Note that no copy of buffer will be made, so it must stay valid until callback is called.

Available since:2.44


buffer An array of guint8

 The length of the array is specified in the count argument.
 The data is owned by the caller of the function.
count gsize

io_priority int

The io priority of the request.

cancellable GCancellable

Optional GCancellable object, NULL to ignore.

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

Callback to call when the request is satisfied.

user_data gpointer
