Given the following information about memory management in C++:
-----
The c-runtime dynamic memory manager (and most other commercial memory
managers) has issues with fragmentation similar to a hard drive file
system.
Over time, the more often use call new/delete or alloc/free, there
will be
gaps and fragments in the heap. This can lead to inefficient use of
available memory, as well as cache-hit inefficiencies.

Hi All,
I use new to allocate some memory,even I doesn't use delete to release them.
When my Application exit, OS will release them.
Am I right?
If I'm right, how about Thread especally on Solaries OS?
This means that I use new to allocate memory in one Thread and doesn't use
delete to release them.

Hi,
I've tried to write the *simplest* memory allocator possible. I think it
would be useful in many cases such as allocating memory on stack as a
poor man's garbage collection perhaps.
I was hoping the clc crowd had some ideas for making it even simpler!
In-lined below the full program (132 lines). It's a circular singular
linked list of "cells" inspired by the one in Plauger's text

Hi there,
i've got an STL map with something like this ( map<string, Object*>
xyz; )
What happens when I call xyz.clear()?
Is only the map cleared or the map and the Objects, so that the memory
is free again?
Have I to delete every single Object?
Thanks for replying,
Jan

Suppose that you have a module that always allocates
memory without ever releasing it because the guy that
wrote it was lazy, as lazy as me.
Now, you want to reuse it in a loop. What do you do?

I have a situation where I need to be able to allocate chunks on
unmapped virtual memory.
Because the memory I'm allocating isn't mapped, I can't use a normal
memory allocator, as most of them want to store their metadata about the
free list in the unused holes in the heap. Instead, I need a memory
allocator that stores its metadata out-of-line (perversely enough, a
simple malloc() heap would be fine for that).
Does anyone know of...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
