getcolor

Syntax

#include <graphics.h>

int getcolor(void);

Description

getcolor returns the current drawing color. The drawing color is the value to which pixels are set when lines and so on are drawn. For example, in CGAC0 mode, the palette contains four colors: the background color, light green, light red, and yellow. In this mode, if getcolor returns 1, the current drawing color is light green.

Return Value

getcolor returns the current drawing color.

Windows Notes

In the winbgim version, the user might set the drawing color to an RGB color. Therefore, the return value from getcolor might be an ordinary BGI color (integer from 0 to 15) or an RGB color.
