     <function>mysql_list_fields</function> retrieves information
     about the given table name. Arguments are the database and
     the table name. A result pointer is returned which can be used
     with <function>mysql_field_flags</function>,
     <function>mysql_field_len</function>,
     <function>mysql_field_name</function>, and
     <function>mysql_field_type</function>.

       The above example would produce the following output:
       <screen>
<![CDATA[
field1
field2
field3

     For downward compatibility <function>mysql_listfields</function>
     can also be used. This is deprecated however.

    <!-- TODO: this is equiv. with 'select * from $table where &false;,'
         which implies you can better use the field-research functions
         on a real query, that saves you one mysql-query.
