10 void _nc_freeall(void);
12 void _nc_free_and_exit(int);

15 These functions are used to simplify analysis of memory leaks in the
16 ncurses library. They are normally not available; they must be config‐
17 ured into the library at build time using the --disable-leaks option.
18 That compiles-in code that frees memory that normally would not be
19 freed.
20 Any implementation of curses must not free the memory associated with a
22 screen, since (even after calling endwin), it must be available for use
23 in the next call to refresh. There are also chunks of memory held for
24 performance reasons. That makes it hard to analyze curses applications
25 for memory leaks. To work around this, one can build a debugging ver‐
26 sion of the ncurses library which frees those chunks which it can, and
27 provides these functions to free all of the memory allocated by the
28 ncurses library.
29 The _nc_free_and_exit function is the preferred one since some of the
31 memory which is freed may be required for the application to continue
32 running. Its parameter is the code to pass to the exit routine.

35 These functions do not return a value.

38 These functions are not part of the XSI interface.
