GLibSourceadd_child_source
since: 2.28
Declaration [src]
void
g_source_add_child_source (
GSource* source,
GSource* child_source
)
Description [src]
Adds child_source to source as a ‘polled’ source.
When source is added to a GMainContext, child_source will be
automatically added with the same priority. When child_source is triggered,
it will cause source to dispatch (in addition to calling its own callback),
and when source is destroyed, it will destroy child_source as well.
The source will also still be dispatched if its own prepare/check functions
indicate that it is ready.
If you don’t need child_source to do anything on its own when it
triggers, you can call g_source_set_dummy_callback() on it to set a
callback that does nothing (except return true if appropriate).
The source will hold a reference on child_source while child_source
is attached to it.
This API is only intended to be used by implementations of GSource.
Do not call this API on a GSource that you did not create.
Available since: 2.28
