Using the function mvprintw(rowOffset, colOffset, textToPrint) from Ncurses, when I print a newline character, if colOffset is anything other than 0, I get a rectangle that looks like this:

   xxxxxxxx
x      x
xxxxxxxx

when I want the rest of the rectangle to align with the top

for

#include <ncurses.h>

    void main()
    {
        initscr();
        mvprintw(7,3,"xxxxxxxx\nx      x\nxxxxxxxx\n");
        refresh();
    }

How can I fix this?

You can create a window, which starts at 7,3, and writes to the window will wrap on newline to column-offset 3, e.g.,

#include <ncurses.h>

void main()
{
    WINDOW *w;
    initscr();
    w = newwin(10,20, 7, 3);
    wprintw(w, "xxxxxxxx\nx      x\nxxxxxxxx\n");
    wrefresh(w);
    wgetch(w);
}

This creates a 10-line window. You could create a larger one, by taking into account the actual screen-size (e.g., LINES).
