generate_instances

Description:

public void generate_instances (long start, long end, Cancellable? cancellable, owned CalRecurInstanceFn cb)

Does a combination of get_object_list () and e_cal_client_recur_generate_instancess().

Unlike generate_instances_sync (), this returns immediately and the cb callback is called asynchronously.

The callback function should do a @ref of the calendar component it gets passed if it intends to keep it around, since it will be unref'ed as soon as the callback returns.

Parameters:

start	Start time for query.
end	End time for query.
cancellable	a Cancellable; can be null
cb	Callback for each generated instance.
cb_data	Closure data for the callback.
destroy_cb_data	Function to call when the processing is done, to free `cb_data`; can be null.
