								<p><a name="index-bfd_005fhash_005ftraverse-1389"></a>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><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.
