</PRE><H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       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 <STRONG><A HREF="curs_initscr.3x.html">endwin(3x)</A></STRONG>), it must be available for
       use in the next call to <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>.  There are also chunks  of  memory
       held for performance reasons.  That makes it hard to analyze curses ap-
       plications for memory leaks.  When using the specially  configured  de-
       bugging 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:

       <STRONG>_nc_freeall</STRONG>
            This frees (almost) all of the memory allocated by ncurses.

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

       <STRONG>_nc_free_tinfo</STRONG>
            Use  this  function  if only the low-level terminfo functions (and
            corresponding library) are used.  Like <STRONG>_nc_free_and_exit</STRONG>, 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 <STRONG>--disable-leaks</STRONG> op-
       tion.   That compiles-in code that frees memory that normally would not
       be freed.

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


</PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       These functions do not return a value.


</PRE><H2><a name="h2-PORTABILITY">PORTABILITY</a></H2><PRE>
       These functions are not part of X/Open Curses; nor do other implementa-
       tions of curses provide a similar feature.
