How to read from the window and compare in Ncurses?

How would I go about having ncurses look at a coordinate, read what character is there, and see if it is the same as an other character? I've been trying to use inch(), but I don't think I'm doing it right. Here's the portion of the code I'm struggling with.

Code:
//Code to scroll left
chtype inch(void);
chtype winch(WINDOW *win);
chtype mvinch(int y, int x);
chtype mvwinch(WINDOW *win, int y, int x);
int scrollX = 0;
int scrollY = 0;
int tempscrollX = 0;
int checkfarend = 1; //Checks to see if there is already an X on the right when looping
else if(CX == -1 ||CY == -1)
{
    while (scrollY < height)
    {
        while (scrollX < width)
        {
            if (inch(scrollX,ScrollY) == 'X')
            {
                tempscrollX = scrollX - 1;
                if(tempscrollX < 0)
                {
                    tempscrollX = width - 1;
                    while(checkfarend == 1)
                    {

                        if(inch(tempscrollX,scrollY) == 'X')
                        {
                            tempscrollX--;
                        }
                        else
                        {
                            checkfarend = 0;
                        }
                    }
                }
                mvaddch(scrollY,tempscrollX,'X');
                mvaddch(scrollY,scrollX,' ');
                checkfarend = 1;
            }
            else
            {
                scrollX++;
            }
            scrollX = 0;
            scrollY++;
        }
    }
    scrollX = 0;
    scrollY = 0;
}

I'm on 32-bit ubuntu, version 14.10.
Thanks for the help!
