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