Virtual Method
GioPollableOutputStreamcreate_source
since: 2.28
Declaration [src]
GSource*
create_source (
GPollableOutputStream* stream,
GCancellable* cancellable
)
Description [src]
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.
The behaviour of this method is undefined if
g_pollable_output_stream_can_poll() returns FALSE for stream.
Available since: 2.28
