Описание (Description)

These functions are used to simplify analysis of memory leaks in
       the ncurses library.

       Any implementation of curses must not free the memory associated
       with a screen, since (even after calling endwin(3X)), it must be
       available for use in the next call to refresh(3X).  There are
       also chunks of memory held for performance reasons.  That makes
       it hard to analyze curses applications for memory leaks.  When
       using the specially configured debugging version of the ncurses
       library, applications can call functions which free those chunks
       of memory, simplifying the process of memory-leak checking.

       Some of the functions are named with a '_nc_' prefix because they
       are not intended for use in the non-debugging library:

       _nc_freeall
            This frees (almost) all of the memory allocated by ncurses.

       _nc_free_and_exit
            This frees the memory allocated by ncurses (like
            _nc_freeall), and exits the program.  It is preferred over
            _nc_freeall since some of that memory may be required to
            keep the application running.  Simply exiting (with the
            given exit-code) is safer.

       _nc_free_tinfo
            Use this function if only the low-level terminfo functions
            (and corresponding library) are used.  Like
            _nc_free_and_exit, it exits the program after freeing
            memory.

       The functions prefixed '_nc' are normally not available; they
       must be configured into the library at build time using the
       --disable-leaks option.  That compiles-in code that frees memory
       that normally would not be freed.

       The exit_curses and exit_terminfo functions call
       _nc_free_and_exit and _nc_free_tinfo if the library is configured
       to support memory-leak checking.  If the library is not
       configured to support memory-leak checking, they simply call
       exit.

Портативность (Portability)

These functions are not part of X/Open Curses; nor do other
       implementations of curses provide a similar feature.
