_nc_freeall _nc_free_and_exit - curses memory-leak
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 com-
piles-in code that frees memory that normally would not be
Any implementation of curses must not free the memory as-
sociated 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 rea-
sons. 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.
