60 These functions are used to simplify analysis of memory leaks in the
61 ncurses library. They are normally not available; they must be config-
62 ured into the library at build time using the <STRONG>--disable-leaks</STRONG> option.
63 That compiles-in code that frees memory that normally would not be
66 Any implementation of curses must not free the memory associated with a
67 screen, since (even after calling <STRONG>endwin</STRONG>), it must be available for use
68 in the next call to <STRONG><A HREF="curs_refresh.3x.html">refresh(3x)</A></STRONG>. There are also chunks of memory held
69 for performance reasons. That makes it hard to analyze curses applica-
70 tions for memory leaks. To work around this, one can build a debugging
71 version of the ncurses library which frees those chunks which it can,
72 and provides these functions to free all of the memory allocated by the
75 The _nc_free_and_exit function is the preferred one since some of the
76 memory which is freed may be required for the application to continue
77 running. Its parameter is the code to pass to the exit routine.
