							 |

| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								<p>You must define a structure for an entry in the hash table,
							 | 
						||
| 
								 | 
							
								and a structure for the hash table itself.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								   <p>The first field in the structure for an entry in the hash
							 | 
						||
| 
								 | 
							
								table must be of the type used for an entry in the hash table
							 | 
						||
| 
								 | 
							
								you are deriving from.  If you are deriving from a basic hash
							 | 
						||
| 
								 | 
							
								table this is <code>struct bfd_hash_entry</code>, which is defined in
							 | 
						||
| 
								 | 
							
								<code>bfd.h</code>.  The first field in the structure for the hash
							 | 
						||
| 
								 | 
							
								table itself must be of the type of the hash table you are
							 | 
						||
| 
								 | 
							
								deriving from itself.  If you are deriving from a basic hash
							 | 
						||
| 
								 | 
							
								table, this is <code>struct bfd_hash_table</code>.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								   <p>For example, the linker hash table defines <code>struct
							 | 
						||
| 
								 | 
							
								bfd_link_hash_entry</code> (in <code>bfdlink.h</code>).  The first field,
							 | 
						||
| 
								 | 
							
								<code>root</code>, is of type <code>struct bfd_hash_entry</code>.  Similarly,
							 | 
						||
| 
								 | 
							
								the first field in <code>struct bfd_link_hash_table</code>, <code>table</code>,
							 | 
						||
| 
								 | 
							
								is of type <code>struct bfd_hash_table</code>.
