+This will replace all open file descriptors in the kernel that points
+to the listed ttys by a dummy that will deny further reading/writing
+to the device. It also send the signals SIGHUP/SIGCONT to the processes
+which have file descriptors open on the listed ttys.

+.SH RETURN VALUE
+On success, zero is returned.  On error, 1 is returned.
