<p>
        The hash table structure. The <code>array</code> member points to the hash table
        entries. The <code>size</code> member counts the total number of valid and invalid
        entries in the table. The <code>nr</code> member keeps track of the number of
        valid entries.
</p>
</dd>
<dt class="hdlist1">
<code>struct hash_table_entry</code>
</dt>
<dd>
<p>
        An opaque structure representing an entry in the hash table. The <code>hash</code>
        member is the entry&#8217;s hash key and the <code>ptr</code> member is the entry&#8217;s
        value.

<dt class="hdlist1">
<code>init_hash</code>

<p>
        Initialize the hash table.

        Release memory associated with the hash table.

<dt class="hdlist1">
<code>insert_hash</code>
</dt>
<dd>
<p>
        Insert a pointer into the hash table. If an entry with that hash
        already exists, a pointer to the existing entry&#8217;s value is returned.
        Otherwise NULL is returned.  This allows callers to implement
        chaining, etc.
</p>
</dd>
<dt class="hdlist1">
<code>lookup_hash</code>
</dt>
<dd>
<p>
        Lookup an entry in the hash table. If an entry with that hash exists
        the entry&#8217;s value is returned. Otherwise NULL is returned.
</p>
</dd>
<dt class="hdlist1">
<code>for_each_hash</code>
</dt>
<dd>
<p>
        Call a function for each entry in the hash table. The function is
        expected to take the entry&#8217;s value as its only argument and return an
        int. If the function returns a negative int the loop is aborted
        immediately.  Otherwise, the return value is accumulated and the sum
        returned upon completion of the loop.
