    Problem calling a function

    Hello,
    I have to include a function that have been given to me in a program to set text and background color. That's the function:
    Code:
    void TextColor(int fontcolor,int backgroundcolor,HANDLE screen)
    {
       unsigned short color_attribute;
       color_attribute = backgroundcolor;
       color_attribute = _rotl(color_attribute,4) | fontcolor;
       SetConsoleTextAttribute(screen,color_attribute);
    }
    However I'm a noob and I don't know how to call it. I've tried TextColor(RED,BLACK) but compiler (dev-c++) gives me an error (to few arguments for TextColor).
    Can you help me?

    Obviously it expects 3 arguments, but you only give it 2.

    Thanks for the quick answer but what is supposed to be the third argument I don't know what a HANDLER is.

    I'm a noob also so take this with caution...

    Do you really want the function declared as void? I would think if you're changing the settings as you are you would want it to return something.

    experts please chime in.

    I can only guess it wants the handle to the console...
    Something like:
    Code:
    TextColor( RED, BLACK, GetConsoleWindow() );
