Hello! I am working on dividing a single C file into several files.
Now I encounter a problem about the global variables
and can not find a way to solve it.
All global variables and codes used to be in that single file, that
worked OK. But when I divdie that file into several ones, I
have many "invalid use of undefined type" errors.
The four files are main.c, main.h, readLP.h, and readLP.c.
In readLP.h

I am trying to create a message box that allows you to enter a name
then display that name on a window. The program uses win32 but that is
not the issue. I want have a global buf variable. So that it can be
filled in the window then displayed in the main window.
Here is what I have
char * buf = NULL; //In my min program.
extern char * buf; // This is the section where I want buf displayed.

I have 3 files (see below: a.h, w.c, ww.c). I would like to use a
single x (declared somewhere) which would global to both compilation
units: w.c & ww.c. No matter where I place the "extern" qualifier - it
appears to work: x is shared between w.c and ww.c. Or if I simple
don't use "extern", it works. Why? What is the correct (or simply
preferred) usage?

I have a program that uses a large lookup table, provided as a large
array in the source:
static int bigtbl={123, 456,
/* etc. etc. */
9999 };
Now this table is pretty big, and having it clutter up my main source
file is quite ugly. So I'd like to put it in a separate file and
#include that.

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 am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
