    I think you need to rephrase that question.

    how would you use this?

    Would you just compare the int returned with the value provided?

    Does it work with getche()?

    I am using DEV, if that effects it.
    Compilers:
    GCC on Red Hat 8.1 (Primary)
    GCC on Mac OS X 10.2.4 (Secondary)

    Others:
    MinGW on XP

    Code:
    <headers...>
    #include "keys.h"
    
    int main()
    {
       int keys;
       keys=my_getch();
       if (keys==K_LEFT)
       {
          printf("left key was pressed");
       }
       system("PAUSE");
       return 0;
    }
    
    
    int my_getch ()
    {
       int input=getch();
       if (input==224) 
          input=getch();
       else if (input==0)
          input=256+getch();
       return input;   
    }

    btw its been a lil while since i last programmed so there might be a small mistake havn't compiled yet should work with dev-c++ (waht i use)

    Code:
    #include <iostream>
    #include <stdlib.h>
    #include "keys.h"
    #include <conio.h>
    
    using namespace std;
    
    int move = 0;
    char key;
    int x = 0;
    int y = 0;
    
    int main()
    {
          
          do
           {
            key = getche();
            move = (char)key;
              if(move == K_UP)
               y--;
              else if(move == K_DOWN)
               y++;
              else if(move == K_LEFT)
               x--;
              else if(move == K_RIGHT)
               x++;
           }while(move != K_ESC);
          
          system("PAUSE");
          return 0;
    }
    Btw, look up the function kbhit()...

    EDIT: It looks like I took way too long on that post before red_baron beat me out.

    red_baron, TechWin... that will not work in a Win32 console... well, it will compile; But it will not work properly.

    You need to use virtual keys...

    I was doing that for Inquirer; for some reason I was thinking he wanted it in console for Dev.

    I'm guessing NULL will indicate an error with getch();
    NULL = 0
