Hi group,
I'm having some difficulty figuring out the most portable way to read 24
bits from a file. This is related to a Base-64 encoding.
The file is opened in binary mode, and I'm using fread to read three
bytes from it. The question is though, where should fread put this? I
have considered two alternatives, but neither seem like a good idea:
In most cases, the width of a char is 8 bits, so an array of 3 chars

Hi there.
I'm just learning c++, and this is driving me nuts.
I'm trying to save image files generated in a for loop with a filename
built using strcat with:
- a char base file name
+ a character to identify the individual files that is indexed from a
char array by the int index of the for loop
+ a char file extension.

A colleague asked me something along the lines of the following today.
For some type X he has:
X* px = new X;
Then he wants to convert px to a char* (I'm guessing for the purpose of
serializing the object array).
I can think of three ways to do this:

I'm trying to use a C++ .lib from C# (I tried the Interop group will no
results).
I have a working wrapper DLL (I can get back simple things like int), but
I'm having issues dealing with an array of bytes.
For example, the .lib contains this function:
int create(int id, int scale, unsigned char *image);
In the wrapper DLL I have this function:

Hi,
I am biginner in C++ and I tried to combine two memory buffers of TIFF image data to one so that to save it as one image. ie: left half image + right half image = a full image. That was not successfull. The code part is:
char * buf1 = (char *)malloc(imageleft.width * image1.length); // for left image
char * buf2 = (char *)malloc(imageright.width * image2.length); // for right image
// for final image
char * buf3 = (char...

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...
