       _nc_freeall _nc_free_and_exit - curses memory-leak checking


       #include <curses.h>

       void _nc_freeall(void);
       void _nc_free_and_exit(int);


       These  functions  are  used to simplify analysis of memory leaks in the
       ncurses library.   They  are  normally  not  available;  they  must  be
       configured  into  the  library  at build time using the --disable-leaks
       option.  That compiles-in code that frees memory  that  normally  would
       not be freed.

       Any implementation of curses must not free the memory associated with a
       screen, since (even after calling endwin), it must be available for use
       in  the next call to refresh.  There are also chunks of memory held for
       performance reasons.  That makes it hard to analyze curses applications
       for  memory  leaks.   To  work  around  this, one can build a debugging
       version of the ncurses library which frees those chunks which  it  can,
       and provides these functions to free all of the memory allocated by the
       ncurses library.

       The _nc_free_and_exit function is the preferred one since some  of  the
       memory  which  is freed may be required for the application to continue
       running.  Its parameter is the code to pass to the exit routine.


       These functions do not return a value.


       These functions are not part of the XSI interface.
