- * Get a seed to use in conjunction with random functions.
+ * Get random data.
+ *
+ * This function can be called repeatedly to generate more random bits
+ * as needed. It is generally quite slow, and usually used to seed a
+ * PRNG.  As it uses /dev/urandom and /dev/random, the quality of the
+ * returned random data depends on the platform.
