Virtual Method

GioDatagramBasedcreate_source

since: 2.48

Declaration

GSource*
create_source (
  GDatagramBased* datagram_based,
  GIOCondition condition,
  GCancellable* cancellable
)

Description

Creates a GSource that can be attached to a GMainContext to monitor for the availability of the specified condition on the GDatagramBased. The GSource keeps a reference to the datagram_based.

The callback on the source is of the GDatagramBasedSourceFunc type.

It is meaningless to specify G_IO_ERR or G_IO_HUP in condition; these conditions will always be reported in the callback if they are true.

If non-NULL, cancellable can be used to cancel the source, which will cause the source to trigger, reporting the current condition (which is likely 0 unless cancellation happened at the same time as a condition change). You can check for this in the callback using g_cancellable_is_cancelled().

Available since: 2.48

Type: GSource
