What would be the common sense way of finding a binary pattern in a
..bin file, say some 200 bytes, and replacing it with an updated pattern
of the same length at the same offset?
Also, the pattern can occur on any byte boundary in the file, so
chunking through the code at 16 bytes a frame maybe a problem. The
file itself isn't so large, maybe 32 kbytes is all and the need for
speed is not so great, but the need for accuracy in the...

A signed int reserves one bit to signify whether a number is positive or
negative. In light of this, a colleague asked me whether there existed an
int in C++ that was -0, a zero with the negative bit set. I was intrigued
by this, so I tried the following code:
#include <stdio.h>
int main(int, char**) {
int a(-0);
printf("a=%d\n", a);

What does binary mode for an ofstream object do anyway? Despite which
mode the stream uses, operator << writes numeric value as their ASCII
representation.
I read on the Internet that it is possible to change the behavior of
operator << so it will stream numeric values as their actual values
when an ofstream is in binary mode. I did not, however, find any
information on how this can be accomplished. What is involved in
getting this...

§27.4.2.1.4 Type ios_base::openmode
Says this about the std::ios::binary openmode flag:
*binary*: perform input and output in binary mode (as opposed to text mode)
And that is basically _all_ it says about it. What the heck does the binary
flag mean?

Hi all,
I try to create a tool to check the delta (diff) of 2
binaries and create the delta binary. I use binary
formatter (serialization) to create the delta binary. It
works fine but the delta binary is pretty huge in size. I
have 1 byte file and 2 bytes file, the delta should be 1
byte but somehow it turns out to be 249 bytes using binary
formatter. I guess serialization has some other things
added to the delta file.

I'm trying to read some binary data from a file created by another
program. I know the binary file format but can't change or control the
format. The binary data is organised such that it should populate a
series of structures of specified variable composition.
I have the structures created OK, but actually reading the files is
giving me an error. Can I ask a simple question to start with:

I have to output data into a binary file, that will contain data
coming from a four channel measurement instrument.
Since those data have to be read from another C program somewhere
else, the reading program must know how many channels have been
acquired, date, time, and so on. I mean that the position of each
datum is not fixed in the file but depends on the conditions when
acquired.
That is, I need something like a header in the file to...

I can't seem to append a string to the end of a binary file. I'm using
the following code:
fstream outFile("test.exe", ios::in | ios::out | ios::binary |
ios::ate | ios::app)
outFile.write("teststring", 10);
outFile.close();
If I leave out the ios::ate and ios::app modes my string is written to
the start of the file as I'd expect but I want to write the data to

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...

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...
