Hi, everyone,
A coworker and I have been pondering a memory allocation problem that we're
having with a very large process. Our joint research has led us to the
conclusion that we may have to replace the STL allocator. But, before I
even attempt something like this, I wanted to ask some questions to this
group:
1) We read online that STL caches allocated memory so that containers and
their contents that are freed at one point in...

Hi all,
I saw this code in the book "Accelerated C++" (chapt 11, iirc):
template <class T> class Vec {
...
std::allocator<T> alloc; // object to handle memory allocation
// ??would static member work here??:
// static std::allocator<T> alloc;

If you specify an allocator in an STL container is it a requirement that
the allocator allocates object of the right type, or can you assume that
the container will rebind the allocator to the correct type?
For example I tried the following code which uses a 'wrong' allocator and
was slightly surrised to find it compiles on the three compilers I tried
it on
#include <vector>
#include <memory>

Hi,
can anybody tell me where I can get the boiler plate code for
std::allocator. I need to have my version of new and delete called and
want to get reference code. My compilers headers are all over the place
with #ifdefs and what not, I'd like a clean copy.
thanks much

Why won't the compiler let me write:

Hi,
I've written allocator for STL vectors, which take all memory from my heap.
But I don't have any idea to implement the same for Maps.
As maps take Key and Values. So should I use the same allocator for both data types, or the allocator for map should ahve different signature???
-Thanks

I tested the speed of a simple program like this:
//------------------------------------------------------------
#include <list>
#include <boost/pool/pool_alloc.hpp>
int main()
{
typedef std::list<intList_t; // default allocator
//typedef std::list<int, boost::pool_allocator<int List_t;

Hi,
I'm following the example in "C++ Templates: The Complete Guide",
section 5.4 Template Template Parameters.
It's basics/stack8.hpp example has a statement of "#include <allocator>",
but I got an error for it.
$ cat -n allocator.cc
1 #include <allocator>

Hello all C++ expert programmer,
i have wrote partial general allocator for my container.
After reading standard C++ library and code guru article, i have
several questions.
1. Why allocator write forward declaration then allocation for void*
rather than directly wrote allocator first ?

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,...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....

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...
