NAME¶
_nc_freeall _nc_free_and_exit -
curses memory-leak checking
SYNOPSIS¶
#include <curses.h>
void _nc_freeall(void);
void _nc_free_and_exit(int);
DESCRIPTION¶
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.
RETURN VALUE¶
These functions do not return a value.
PORTABILITY¶
These functions are not part of the XSI interface.
