+.SH DESCRIPTION
+The
+.B wake_up
+function is the opposite of the
+.BR sleep_on "(9)"
+function in that it awakens processes that have gone to sleep using
+the same condition variable. All the processes sleeping on the given
+condition are awakened. If there are no processes sleeping on the
+condition, then none are affected.
+.PP
+Unlike the
+.BR sleep_on "(9)"
+function,
+.B wake_up
+does not block and may be called by interrupt handlers. It is in fact
+the principle means of synchronizing with interrupt events.
+.PP
+If the
+.I condition
+parameter is NULL, or there are no processes sleeping on
+.I condition,
+the call to
+.B wake_up
+is a no-op.
+.SH "RETURN VALUE"
+None.
