在MySQL数据库中应当如何实施info()函数

ulonglong data_file_length;           
/* Length off data file */
ulonglong max_data_file_length;       
/* Length off data file */
ulonglong index_file_length;
ulonglong max_index_file_length;
ulonglong delete_length;              
/* Free bytes */
ulonglong auto_increment_value;
ha_rows records;                      
/* Records in table */
ha_rows deleted;                      
/* Deleted records */
ulong raid_chunksize;
ulong mean_rec_length;         
/* physical reclength */
time_t create_time;                   
/* When table was created */
time_t check_time;
time_t update_time;
