getmaxcolor

Returns maximum color value that can be passed to the setcolor function.

Defined in header <graphics.h>

Syntax

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

Portability

Remarks

getmaxcolor returns the highest valid color value for the current graphics driver and mode that can be passed to setcolor.

For example, on a 256K EGA, getmaxcolor always returns 15, which means that any call to setcolor with a value from 0 to 15 is valid. On a

getmaxcolor returns a value of 1.

Return value

getmaxcolor returns the highest available color value.
