+ | ==== Description of getmaxmode ==== | ||
+ | <code c> | ||
+ | getmaxmode lets you find out the maximum mode number for the currently | ||
+ | loaded driver, directly from the driver. This gives it an advantage over | ||
+ | getmoderange, which works for Borland drivers only. The minimum mode is | ||
+ | 0. | ||
