My C program has the following:
static int skip_space(FILE *fp, int *line, int c)
{
int i = 0;
if(feof(fp)) { printf("in skip feof ...\n"); }
printf("in skip start fp=%p line=%d c=%d\n", fp, *line, c);
while ((c == ' ' || c == '\t') && !feof(fp)) {
printf("i=%d\n", i++);
if(feof(fp)) { printf("in skip feof\n"); break;}
c = getc(fp);

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;

Assuming all the values of int are in the range of unsigned char, what
happends if getc returns EOF?
Is it possible that EOF was the value of the byte read?
Does that mean that code aiming for maximum portability needs to check
for both feof() and ferror()?
(for example, if both feof() and ferror() return 0 for the stream when
getc() returned EOF, consider EOF a valid byte read)
To me, that seems to be the case, but maybe the standard...

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...
