_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 con-
figured 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 ap-
plications 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.

I am using Darwin on Mac OS X.I.I (new to both Unix and C++).
I downloaded the ncurses library from http://prdownloads.sourceforge.net/gnu-darwin/ncurses-5.2.tgz,
but I don't know what to do with it now. Stuffit has expanded the archive, but I still have the original .tgz as well (if that's... (1 Reply)
Hi!! Experts,
Any ideas how to check for the memory leaks in a process during performance testing?? I dont use purify.. Any way of finding it out using default S/W in HP UX-11
Can U gimme pointers to site having good scripts/tutorials on performance testing??
Thanx in Advance..

Hi Dear,
I have written a small C/C++ aplication which is using ncurses library. When the application runs, some times some unknown characters are displayed on the screen. It happens some times and on some pc's. I have used "mvwprintw" for displaying text of my own will and proper use of... (1 Reply)

Hi,
This is my 1st post here. I am facing a rather weired problem. I have a C++ binary running on HP-UX. The output of top as well as glance shows periodic increase in memory. But when i use gdb to detect it, i dont get the desired output...gdb says...no leaks found. Just to mention that I have... (2 Replies)

I am new to this programming with ncurses. I want to work out few examples on this ncurses. I jus want to know whether this ncurses works with Ubuntu OS? I found tat ncurses doesn come with AIX OS, may be it could be installed as a SupportPac or something, not sure about it.
Can u please... (4 Replies)
Hi,
I am facing one strange situation while using strftime() to get current date and time in C.
it leaks memory with %T
strftime(L_StrDate,30,"%d-%b-%C%y %T", localtime((time_t *)&tv.tv_sec)) ;
and when i use another option then no memory leak like

Hi, all -
New to ncurses, rusty as hell with UNIX, I"m sure I'm going to have lots of questions. What forum is best for ncurses questions? Currently I'm experiencing configuration issues (I believe). I'm running Mac 10.6, and using the Terminal utility.
Thanks! (3 Replies)
I have written this code in C which reads a very large collection of text files and does some processing. The problem with this code is that there are memory leaks which I am not able to figure out as to where the problem is. When I run this code, and see the memory usage using top command, then I...

I had a situation where the server was basically unresponsive and apparently it was out of memory. I ran top and free commands and got the following outputs. I figured it was out of memory because there was no free swap left. But quite frankly I'm perplexed by this output, why does it appear that... (3 Replies)
I am using ncurses to develop a user interface. Perhaps I should be using something else, but I am reasonably comfortable with ncurses and don't really want to climb another learning curve at this time.
One problem I have dealt with for many years is ncurses' colors. I have simply been... (23 Replies)
Hi, all,
I'm writing a BBS telnet client, and am trying to implement a status bar into it, at the bottom of the screen.
I am using NCurses to accomplish this. So far, it appears to be working, that is, upon connecting to BBS, it
will display the status bar, and then quickly disappear.
