+ * A clock source registers using mISDN_register_clock:
+ * name = text string to name clock source
+ * priority = value to priorize clock sources (0 = default)
+ * ctl = callback function to enable/disable clock source
+ * priv = private pointer of clock source
+ * return = pointer to clock source structure;
+ *
+ * Note: Callback 'ctl' can be called before mISDN_register_clock returns!
+ * Also it can be called during mISDN_unregister_clock.
+ *
+ * A clock source calls mISDN_clock_update with given samples elapsed, if
+ * enabled. If function call is delayed, tv must be set with the timestamp
+ * of the actual event.
+ *
+ * A clock source unregisters using mISDN_unregister_clock.
+ *
+ * To get current clock, call mISDN_clock_get. The signed short value
+ * counts the number of samples since. Time since last clock event is added.
