-/* XXX: This is going to be removed soon and SPOP internals
- *      reimplemented.
- *
- * This is a version of dictGetRandomKey() that is modified in order to
- * return multiple entries by jumping at a random place of the hash table
- * and scanning linearly for entries.
- *
- * Returned pointers to hash table entries are stored into 'des' that
- * points to an array of dictEntry pointers. The array must have room for
- * at least 'count' elements, that is the argument we pass to the function
- * to tell how many random elements we need.
- *
- * The function returns the number of items stored into 'des', that may
- * be less than 'count' if the hash table has less than 'count' elements
- * inside.
- *
- * Note that this function is not suitable when you need a good distribution
- * of the returned items, but only when you need to "sample" a given number
- * of continuous elements to run some kind of algorithm or to produce
- * statistics. However the function is much faster than dictGetRandomKey()
- * at producing N elements, and the elements are guaranteed to be non
- * repeating. */
