 22.2.3.38 `mysql_list_fields()'
 ...............................
 
 `MYSQL_RES *mysql_list_fields(MYSQL *mysql, const char *table, const
 char *wild)'
 
 Description
 ...........
 
 Returns a result set consisting of field names in the given table that
 match the simple regular expression specified by the `wild' parameter.
 `wild' may contain the wildcard characters `%' or `_', or may be a
 `NULL' pointer to match all fields.  Calling `mysql_list_fields()' is
 similar to executing the query `SHOW COLUMNS FROM TBL_NAME [LIKE WILD]'.
 
 Note that it's recommended that you use `SHOW COLUMNS FROM TBL_NAME'
 instead of `mysql_list_fields()'.
 
 You must free the result set with `mysql_free_result()'.
 
 Return Values
 .............
 
 A `MYSQL_RES' result set for success.  `NULL' if an error occurred.
 
 Errors
 ......
 
 `CR_COMMANDS_OUT_OF_SYNC'
      Commands were executed in an improper order.
 
 `CR_SERVER_GONE_ERROR'
      The MySQL server has gone away.
 
 `CR_SERVER_LOST'
      The connection to the server was lost during the query.
 
 `CR_UNKNOWN_ERROR'
      An unknown error occurred.
