- * the data is up to the user. When creating or initializing a hash table,
- * the user must supply a pointer to a function for comparing two keys,
- * and a pointer to a function for hashing a key into a numeric value.

- * 3. The count member maintains the number of elements that are presently
- * in the hash table.
- * 4. The maximum count is the greatest number of nodes that can populate this
- * table. If the table contains this many nodes, no more can be inserted,
- * and the hash_isfull() function returns true.
- * 5. The high mark is a population threshold, measured as a number of nodes,
- * which, if exceeded, will trigger a table expansion. Only dynamic hash
- * tables are subject to this expansion.
- * 6. The low mark is a minimum population threshold, measured as a number of
- * nodes. If the table population drops below this value, a table shrinkage
- * will occur. Only dynamic tables are subject to this reduction. No table
- * will shrink beneath a certain absolute minimum number of nodes.
- * 7. This is the a pointer to the hash table's comparison function. The
- * function is set once at initialization or creation time.
- * 8. Pointer to the table's hashing function, set once at creation or
- * initialization time.
- * 9. The current hash table mask. If the size of the hash table is 2^N,
- * this value has its low N bits set to 1, and the others clear. It is used
- * to select bits from the result of the hashing function to compute an
- * index into the table.
- * 10. A flag which indicates whether the table is to be dynamically resized. It
- * is set to 1 in dynamically allocated tables, 0 in tables that are

+ * This is the hash table control structure. It keeps track of information
+ * about a hash table, as well as the hash table itself.
+ * Notes:
+ * 1. Pointer to the hash table proper. The table is an array of pointers to
+ * hash nodes (of type hnode_t). If the table is empty, every element of
+ * this table is a null pointer. A non-null entry points to the first
+ * element of a chain of nodes.
+ * 2. This member keeps track of the size of the hash table---that is, the
+ * number of chain pointers.
+ * 3. The count member maintains the number of elements that are presently
+ * in the hash table.
+ * 4. The maximum count is the greatest number of nodes that can populate this
+ * table. If the table contains this many nodes, no more can be inserted,
+ * and the hash_isfull() function returns true.
+ * 5. The high mark is a population threshold, measured as a number of nodes,
+ * which, if exceeded, will trigger a table expansion. Only dynamic hash
+ * tables are subject to this expansion.
+ * 6. The low mark is a minimum population threshold, measured as a number of
+ * nodes. If the table population drops below this value, a table shrinkage
+ * will occur. Only dynamic tables are subject to this reduction. No table
+ * will shrink beneath a certain absolute minimum number of nodes.
+ * 7. This is the a pointer to the hash table's comparison function. The
+ * function is set once at initialization or creation time.
+ * 8. Pointer to the table's hashing function, set once at creation or
+ * initialization time.
+ * 9. The current hash table mask. If the size of the hash table is 2^N,
+ * this value has its low N bits set to 1, and the others clear. It is used
+ * to select bits from the result of the hashing function to compute an
+ * index into the table.
+ * 10. A flag which indicates whether the table is to be dynamically resized. It
+ * is set to 1 in dynamically allocated tables, 0 in tables that are
+ * statically allocated.
