getmaxmode

Syntax

#include <graphics.h>
int getmaxmode(void);

Description

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.

Return Value

getmaxmode returns the maximum mode number for the current driver.
