.SH SYNOPSIS
|
|
\fB#include <curses.h>\fR
|
|
.sp
|
|
\fBvoid _nc_freeall(void);\fR
|
|
.br
|
|
\fBvoid _nc_free_and_exit(int);\fR
|
|
.SH 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 \fB--disable-leaks\fP option.
|
|
That compiles-in code that frees memory that normally would not be freed.
|
|
.PP
|
|
Any implementation of curses must not free the memory associated with
|
|
a screen, since (even after calling \fBendwin\fP), it must be available
|
|
for use in the next call to \fBrefresh\fP.
|
|
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.
|
|
.PP
|
|
The \fP_nc_free_and_exit\fP 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 \fPexit\fP routine.
|
|
.SH RETURN VALUE
|
|
These functions do not return a value.
|
|
.SH PORTABILITY
|
|
These functions are not part of the XSI interface.
