_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(3X). 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.
