+ *
+ * DESCRIPTION
+ *
+ * Sets global SilcSchedule `schedule' that can be retrieved at any time

+ * to the current thread. Each thread can have their own global scheduler.
+ * If each thread must have global scheduler this must be called in each
+ * thread. If the global scheduler has been set already, new call will
+ * replace the old one.
+ *
+ * This routine is provided only as a convenience function to store
+ * program's or thread's scheduler in one global place. It is not mandatory
+ * to call this function in order to use SilcSchedule.
+ *
+ * Many routines that require SilcSchedule as an argument will call
+ * silc_schedule_get_global if the scheduler is not provided to try to
+ * get global scheduler. Almost all routines in SilcSchedule API will call
+ * silc_schedule_get_global if the SilcSchedule is not provided as argument.
