looking for an explanation for the following:
The functions pairs:

Do the "larger" input functions like scanf, gets, fgets use fgetc to
take input or an operating system call function like read() (I know it
could be any "way", but I'm trying to find out how it's best to "think
of it")?
I've seen some explain it as if they call fgetc internally, then I've
seen some people explain it as if they call some lower level OS system
call like read(). I've even seen some older posts talk about a input

I'm reading "C: A Reference Manual" but still can't understand a
very basic thing: is there any functional difference between
fgetc/fputc and fread/fwrite (when reading/writing one unsigned
char)?
1. Books and documentation on C tell me fread and fwrite is "binary".
What does binary mean in this? Anything to do with opening a file
in binary mode?
2. I'm also sure I've read somewhere on the net that fread and

Hi,
While reading ISO C Standard, I found follow text in 7.19.8.1:
size_t fread(void *restrict ptr, size_t SIZE, ...)
... For each object, SIZE calls are made to the fgetc function
and the results stored, in the order read, in an array of
unsigned char exactly overlaying the object.

My understanding is that cstdio basically is the same as stdio.h except
the functions are in a namspace called std. However when I take a look
at the content of the file cstdio, it has the following lines inside
only:
-------content of cstdio on red hat linux enterprise 3----
#ifndef __CSTDIO__
#define __CSTDIO__
#include <stdio.h>
#endif

I'm having a bit of a problem running a C program I'm working on (compiled in cygwin). There's a way to go, as I'm intent on making sure each bit works before moving on to the next. As it appears now:
# include <stdio.h>
# include <string.h>
int main(void)
{
printf("Fine at line 6");
FILE *source;
char string1;

getc gets the charachter from file stream and points to next charachter, fgetc gets the charachter from file stream and i don't know whether it points to next charachter or not; is that a significant change?
In the help menu of Turbo C, it's given that its a function version of getc macro. what is a function version?

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...
