I have a member function that acts on an object. I would also like to
have a member function that acts on a container of such objects,
using std::for_each. I tried:
#include <algorithm>
#include <functional>
struct bar {
template<typename T> void foo(T const &);
template<typename InIt> void foo(InIt begin, InIt end)

I've got a function that I use a lot when making utility programs
that need to do the same thing to every directory in a tree.
Its prototype is:
unsigned long int CursDirs (void Func(void));
This just applies the fuction Func to every subdirectory of the
current directory. It works fine when I pass it pointers to regular
void-void functions.

What is the exact difference between mem_fun and mem_fun_ref, since in
all examples I looked at, they are used in exactly the same way?

We have ptr_fun to handle functions, mem_fun to handle member functions
that will be called through a pointer, and mem_fun_ref to handle member
functions that will be called through a reference.
First, why do we need to have seperate mem_fun/mem_fun_ref? The first
returns a mem_fun_t, and the second a mem_fun_ref_t. But the only
difference between mem_fun_t and mem_fun_ref_t is that they have
different operator() methods. But since...

Hi,
I am having some problem using std::bind1st() and mem_fun. I want to
bind member function calls to some kind of functor so it can be called
later.
The following works fine for me:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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...
