<a name="index-bfd_005fhash_005ftraverse"></a>
<p>The function <code>bfd_hash_traverse</code> may be used to traverse a
hash table, calling a function on each element.  The traversal
is done in a random order.
</p>
<p><code>bfd_hash_traverse</code> takes as arguments a function and a
generic <code>void *</code> pointer.  The function is called with a
hash table entry (a <code>struct bfd_hash_entry *</code>) and the
generic pointer passed to <code>bfd_hash_traverse</code>.  The function
must return a <code>boolean</code> value, which indicates whether to
continue traversing the hash table.  If the function returns
<code>FALSE</code>, <code>bfd_hash_traverse</code> will stop the traversal and
return immediately.
</p>
