<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.
