+ | ====Syntax of getmodename ==== | ||
+ | <code c> | ||
+ | #include <graphics.h> | ||

+ | |||
+ | |||
+ | ==== Description of getmodename ==== | ||
+ | <code c> | ||
+ | getmodename accepts a graphics mode number as input and returns a string | ||
+ | containing the name of the corresponding graphics mode. The mode names | ||
+ | are embedded in each driver. The return values ("320*200 CGA P1," | ||
+ | "640*200 CGA", and so on) are useful for building menus or displaying | ||
+ | status. | ||
