Method
GioOutputStreamwrite_bytes_async
Declaration [src]
void
g_output_stream_write_bytes_async (
GOutputStream* stream,
GBytes* bytes,
int io_priority,
GCancellable* cancellable,
GAsyncReadyCallback callback,
gpointer user_data
)
Description [src]
This function is similar to g_output_stream_write_async(), 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 g_output_stream_write_async(). 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.
For the synchronous, blocking version of this function, see g_output_stream_write_bytes().
This method completes asynchronously. Use g_output_stream_write_bytes_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
