14. Miscellaneous features

Now you know enough features to write a good curses program, with all bells and whistles. There are some miscellaneous functions which are useful in various cases. Let's go headlong into some of those.

14.1. curs_set()

This function can be used to make the cursor invisible. The parameter to this function should be

    0 : invisible      or
    1 : normal    or
    2 : very visible.

14.2. Temporarily Leaving Curses mode

Some times you may want to get back to cooked mode (normal line buffering mode) temporarily. In such a case you will first need to save the tty modes with a call to def_prog_mode() and then call endwin() to end the curses mode. This will leave you in the original tty mode. To get back to curses once you are done, call reset_prog_mode() . This function returns the tty to the state stored by def_prog_mode(). Then do refresh(), and you are back to the curses mode. Here is an example showing the sequence of things to be done.

Example 12. Temporarily Leaving Curses Mode

/* File Path: basics/temp_leave.c */
#include <ncurses.h>

int main()
    initscr();                      /* Start curses mode */
    printw("Hello World !!!\n");    /* Print Hello World */
    refresh();                      /* Print it on to the real screen */
    def_prog_mode();                /* Save the tty modes          */
    endwin();                       /* End curses mode temporarily      */
    system("/bin/sh");              /* Do whatever you like in cooked mode */
    reset_prog_mode();              /* Return to the previous tty mode*/
                                    /* stored by def_prog_mode()       */
    refresh();                      /* Do refresh() to restore the       */
                                    /* Screen contents          */
    printw("Another String\n");     /* Back to curses use the full    */
    refresh();                      /* capabilities of curses      */
    endwin();                       /* End curses mode          */

    return 0;
