Virtual Method

GioPollableOutputStreamcreate_source

since: 2.28

Declaration

GSource*
create_source (
  GPollableOutputStream* stream,
  GCancellable* cancellable
)

Description

Creates a GSource that triggers when stream can be written, or cancellable is triggered or an error occurs. The callback on the source is of the GPollableSourceFunc type.

As with g_pollable_output_stream_is_writable(), it is possible that the stream may not actually be writable even after the source triggers, so you should use g_pollable_output_stream_write_nonblocking() rather than g_output_stream_write() from the callback.

Available since: 2.28

Parameters

Type: GCancellable

A GCancellable, or NULL.

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

Return value

Type: GSource

A new GSource.

The caller of the function takes ownership of the data, and is responsible for freeing it.
