Method

Gio InputStreamread_all_async

since: 2.44

Declaration [src]


void
g_input_stream_read_all_async (
  GInputStream* stream,
  void* buffer,
  gsize count,
  int io_priority,
  GCancellable* cancellable,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Request an asynchronous read of count bytes from the stream into the buffer starting at buffer.

This is the asynchronous equivalent of g_input_stream_read_all().

Call g_input_stream_read_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.

Available since: 2.44

This method completes asynchronously. Use g_input_stream_read_all_finish() inside the GAsyncReadyCallback to obtain the result of the operation.

Parameters

buffer

Type: An array of guint8

a buffer to read data into (which should be at least count bytes long).

The argument will be set by the function.
The length of the array is specified in the count argument.
The returned data is owned by the instance.

count

Type: gsize

The number of bytes that will be read from the stream.

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 method.

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.
