+ * SilcBool added, SilcTask task,
+ * SilcBool fd_task, SilcUInt32 fd,
+ * SilcTaskEvent event,
+ * long seconds, long useconds,
+ * void *context);
+ *
+ * DESCRIPTION
+ *
+ * Task notify callback. Callback of this type can be set to scheduler
+ * by calling silc_schedule_set_notify and will be called whenever new
+ * task is added or old task is removed. If `added' is TRUE then `task'
+ * is added to scheduler. If `added' is FALSE then `task' will be removed
+ * from the scheduler. If `fd_task' is TRUE the `task' is file descriptor
+ * task and has `fd' is its file descriptor. If `fd_task' is FALSE then
+ * the task is timeout task and `seconds' and `useconds' specify the
+ * timeout. The `context' is the context given to silc_schedule_set_notify.
+ *
+ * NOTES
+ *
+ * The `schedule' is locked while this callback is called. This means that
+ * new tasks cannot be added or removed inside this callback.
+ *
+ * When timeout task expires this callback is not called. This is called
+ * only when task is explicitly deleted from the scheduler. Note that,
+ * when timeout task expires it is removed from the scheduler and `task'
+ * will become invalid.
+ *
+ * If fd task changes its events, this will be called as if it was a new
+ * task with different `event' mask.
