Method

GioOutputStreamwritev_all_async

since: 2.60

Declaration 

void
g_output_stream_writev_all_async (
  GOutputStream* stream,
  GOutputVector* vectors,
  gsize n_vectors,
  int io_priority,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description

Request an asynchronous write of the bytes contained in the n_vectors vectors into the stream. When the operation is finished callback will be called. You can then call g_output_stream_writev_all_finish() to get the result of the operation.

This is the asynchronous version of g_output_stream_writev_all().

Call g_output_stream_writev_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 vectors will be made, so it must stay valid until callback is called. The content of the individual elements of vectors might be changed by this function.

Available since: 2.60

Parameters

vectors

Type: An array of GOutputVector

The buffer containing the GOutputVectors to write.

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

Type: gsize

The number of vectors to write.

io_priority

Type: int

The I/O priority of the request.

cancellable

Type: GCancellable

Optional GCancellable object, NULL to ignore.

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

Type: GAsyncReadyCallback

A GAsyncReadyCallback to call when the request is satisfied.

The argument can be NULL.
user_data

Type: gpointer

The data to pass to callback function.

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