- * Hash_EnumFirst --
- * This procedure sets things up for a complete search
- * of all entries recorded in the hash table.
- *
- * Results:
- * The return value is the address of the first entry in
- * the hash table, or NULL if the table is empty.
- *
- * Side Effects:
- * The information in hashSearchPtr is initialized so that successive
- * calls to Hash_Next will return successive HashEntry's
- * from the table.
