Is there a better way of doing this ?

I am getting the input (left arrow or right arrow)
using the following code:

PHP Code:

---

int grabinput()
{
    char c;
    c = getch();
    
    if ((float) c == 27)
    {
        return 2;
    }
    else if ((float) c == 75)
    {
        return 0;
    }
    else if ((float) c == 77)
    {
        return 1;
    }
    
    fflush(stdin);
    return -1;
}

(returns 2 for escape, 0 for left, 1 for right - keys ... and -1 just in case something else happens)

Is there a better/standard way of doing this ? If so, how ?

Code:

int grabinput(){

      char c;
      c = getch();

      switch((int)c){
            case 27:
                      return 2;
            case 75:
                      return 0;
            //ect
            default:
                      return -1;     
      }
}

Why don't you just put your logic inside of the case statements as oppose to implementing it based on return values?
