I am trying to open a file in the classes contructor. The file is
created and the program even thinks it is open and tries to write to
it with no errors, but when I look at the file it is zero
bytes..nothing was written to it. Here is part of my code if anyone
can help me. I do appreciate it.
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>

(Sorry for cross-posting).
I need to access large files > 2GByte (Linux, WinXP/NTFS)
using the standard C-library calls.
Till today I thought I know how to do it, namely for
Win32:
Use open(), read(), _itelli64(), _lseeki64() with type __int64
Linux/Cygwin:
#define _FILE_OFFSET_BITS 64
Use open(), read(), lseek() with type off_t

Hi all,
I'm trying to read from the txt file 'ip.packets.2.txt' using the read
function. It seems everything ok, but I get a -1 when executing
>>bytesr = read(fdo1, bufread, 2);
The 'open' function returns the file dsc 3. So this seems ok..
Any idea what might be wrong?

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...

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...
