Description [src]
Dispatches the source callback.
Called to dispatch the event source, after it has returned
TRUE
in either its prepare or its check function, or if a ready time
has been reached. The dispatch function receives a callback function and
user data. The callback function may be NULL
if the source was never
connected to a callback using g_source_set_callback()
. The dispatch
function should call the callback function with user_data
and whatever
additional parameters are needed for this type of event source. The
return value of the dispatch function should be G_SOURCE_REMOVE
if the source should be removed or G_SOURCE_CONTINUE
to keep it.
