getmaxy

Returns maximum y screen coordinate.

Defined in header <graphics.h>

Syntax

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

Portability

Remarks

getmaxy returns the maximum (screen-relative) y value for the current graphics driver and mode.

For example, on a CGA in 320x200 mode, getmaxy returns 199. getmaxy is invaluable for centering, determining the boundaries of a region onscreen, and so on.

getmaxy returns the maximum y screen coordinate.
