Syntax

#include <graphics.h>

int getbkcolor(void);

Description

getbkcolor returns the current background color. (See the table in setbkcolor for details.)

Return Value

getbkcolor returns the current background color.

Windows Notes

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