Method

GioPollableOutputStreamcreate_source

Declaration

GSource*
g_pollable_output_stream_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

`cancellable`	`GCancellable`
	A `GCancellable`, or `NULL`.
	The argument can be `NULL`.
	The data is owned by the caller of the function.

Return value

Returns:	`GSource`
	A new `GSource`.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
