Raw mode only works with the Curses input routines [w]getch
    and [w]getstr. Raw mode is not supported with the C RTL
    emulation of UNIX I/O, Terminal I/O, or Standard I/O.

    Format

      #include  <curses.h>

      raw()

      noraw()

1  –  Description

    Raw mode reads are satisfied on one of two conditions: after
    a minimum number (5) of characters are input at the terminal
    or after waiting a fixed time (10 seconds) from receipt of any
    characters from the terminal.

2  –  Example

        /* Example of standard and raw input in Curses package. */

        #include <curses.h>

        main()
        {
            WINDOW *win1;
            char vert = '.',
                 hor = '.',
                 str[80];

            /* Initialize standard screen, turn echo off.  */

            initscr();
            noecho();

            /* Define a user window.  */

            win1 = newwin(22, 78, 1, 1);
            leaveok(win1, TRUE);
            leaveok(stdscr, TRUE);

            box(stdscr, vert, hor);

            /* Reset the video, refresh(redraw) both windows. */

            mvwaddstr(win1, 2, 2, "Test line terminated input");
            wrefresh(win1);

            /* Do some input and output it. */
            nocrmode();
            wgetstr(win1, str);

            mvwaddstr(win1, 5, 5, str);
            mvwaddstr(win1, 7, 7, "Type something to clear screen");
            wrefresh(win1);

            /* Get another character then delete the window. */

            wgetch(win1);
            wclear(win1);

            mvwaddstr(win1, 2, 2, "Test raw input");
            wrefresh(win1);

            /* Do some raw input 5 chars or timeout and output it. */
            raw();
            getstr(str);
            noraw();
            mvwaddstr(win1, 5, 5, str);
            mvwaddstr(win1, 7, 7, "Raw input completed");
            wrefresh(win1);

            endwin();
        }
