+ | int getgraphmode(void); | ||

+ | |||
+ | ==== Description of getgraphmode ==== | ||
+ | <code c> | ||
+ | Your program must make a successful call to initgraph before calling | ||
+ | getgraphmode. | ||
+ | The enumeration graphics_mode, defined in graphics.h, gives names for the | ||
+ | predefined graphics modes. For a table listing these enumeration values, | ||
+ | refer to the description for initgraph. | ||
+ | </code> | ||
