string keystroke(char KeyStroke, string output2){

    while (true==true) {
        KeyStroke = getch();
        if (KeyStroke == 0)
        {
            KeyStroke = getch(); // Even though there are 2 getch() it reads one keystroke
            switch (KeyStroke)
            {
            case UP_ARROW:
                Keystroke1 = "up";
                charpos_calculation(Keystroke1);
            break;
            }
        }

    return output2;
}

Question 1 - When ran my program returns this error .The POSIX name for this item is deprecated
What do I need to do to fix this.

Question 2 - How do I get a keystroke? I defined the up arrow by #define UP_ARROW 25. Is this the right way and the right value.

What I'm trying to figure out is how to get direct keyboard input from the user. How would I do this so the user doesn't have to press enter.

This is a console application using Windows Visual Studio 2012 Express.

Also this is part of my code of a larger game.

Please update your question with the code that includes the error for the POSIX issue. The above doesn't have anything dealing with POSIX threads. Its difficult to identify a solution if we don't have all the information.

Visual Studio points the error I displayed above to the above code. If that is not it, I don't know what it would be. How many lines of code can i paste into my question because I have 700.

I believe that is a warning, not an error. Anyway the compiler is right, of course :-), see the documentation[^] for a fix (that is use _getch[^] instead).

You may test it.

When I use the KeyStroke = _getch. I get this error. IntelliSense: a value of type "int (__cdecl *)()" cannot be assigned to an entity of type "char". What do I need to do to fix this.

You missed the braces:
KeyStroke = _getch();

Sorry for my stupidity.

Just an oversight, I believe.
