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