Hi,
I'm currently trying to create a wrapper that uses C functions but
behaves like ifstream (from fstream.h) - this is because the platform
I'm using (WinCE) doesn't support streams and this is the easiest way
to take a huge project across onto it.
Basically, I've hit a problem. I have no idea how the ifstream class
handles directories. In the code I have (which I didn't write), there
are several places whereby an ifstream stream is...

Hello all,
I am trying to read in lines into a buffer from a file. Normally I would do
this very low-level,
but I have come to the conclusion I must stop doing everything the hard way.
So, I thought I would try
<fstream>. The code below causes an infinite loop in the while() statement.
Debugging, I see that the buffer just has a 0 in
the first position, and nothing else.

Hello all,
I am in a bit of a pickle using the getline function with an ifstream.
It does not seem to work as advertised. Here is my scenario. In a
nutshell, my code needs to pick up a fixed record length flat file
that is generated by an old IBM mainframe. These data fields need to
be read in by my program EXACTLY as they are represented in the file.
Here is an example text file that I used in my test.

Hi.
I ran across a bug in one of my problems and after spending some time
tracking it down i found that the problem arose in a piece of code that
essentially did this:
-----------
ifstream in("in.txt"); if(!in) {cout << "error\n";}
in.close(); if(!in) {cout << "error\n";}
in.close(); if(!in) {cout << "error\n";}

Hi,
I want to unread a few things while I am reading a file. One
solution I know is putback the characters read to the buffer.
But as I need frequent moving file pointer , to a few steps back, I
was thinking of seekg & tellg function. But it is not workings as I
expect....

Hi C++ folks,
I have trouble to open files whose path contains non-ascii characters
with std::ifstream.
For instance let's say i just have a file which has Japanese
characters either in the file path or the file name : 疑問.dat. The
file itself does not contains unicode characters or whatever, it is a
binary file, but the file name, or path, contains non-ascii
characters, here it is Japanese but it could be anything else, i know...

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...
