+.Fd #include <dev/rndvar.h>
+.Va void add_tty_randomness(dev_t dev);

+.Va void add_net_randomness(int isr);

+.Sh DESCRIPTION
+add_{tty,net,blkdev}_randomness routines used to supply data
+for the random data source device for future processing.
+.Pp
+get_random_bytes maybe used to retrive strong random data, just
+as it would by
+.Xr srandom 4
+device.
