Sorry for this very dumb question, but I've clearly got a long way to go!
Can someone please help me pass an array into a function. Here's a starting
point.
void TheMainFunc()
{
// Body of code...
TCHAR myArray;
DoStuff(myArray);

Thanks to all of you because I solved the problem related with my
previous post.
I simply made confusion with pointers to pointers and then succeeded
passing the reference to the first element pointer.
:-))
You were right about by mixed code: quickly writing an example to
clarify the matter I made a C++ program, sorry for the inconvenience.
Anyway, although it all works fine with monodimensional arrays,
I still have a problem with...

hi,
i'm using "gcc version 3.3.3 (Debian)" to compile the program pasted below.
I get the two warnings you can see in the remarks. The second warning is
perfectly OK for me, but the first one I don't understand.
Isn't the "const int *" construct in the signature of func1 a hint for the
user, that func1 doesn't modify **arg? Why then is it dangerous to
pass an alterable argmument?

I am trying to pass a slice from a larger 2-dimensional array to a
function that will work on a smaller region of the array space. The
code below is a distillation of what I am trying to accomplish.
// - - - - - - - - begin code - - - - - - -
typedef int sm_t;
typedef int bg_t;
sm_t sm;
bg_t bg;

The library function 'qsort' is declared thus:
void qsort(void *base, size_t nmemb, size_t size,
int(*compar)(const void *, const void *));
If in my code I write:
int cmp_fcn(...);
int (*fcmp)() = &cmp_fcn;
qsort(..., fcmp);
then everything works. But if instead I code qsort as:

In C++ an overridden virtual function in a derived class must have the exact
same signature of the function which is overridden in the base class, except
for the return type which may return a pointer or reference to a derived
type of the base class's return type.
In .NET the overridden virtual function is similar, but an actual parameter
of the function can be a derived reference from the base class's reference
also.
This dichotomy...

I have an abstract base class defined in an MC++ class library. I then
create a descendent class in a C# class library. This seems to work OK with
the exception of one of the abstract member functions/pure virtual function
that uses a passed in pointer to a long.
Just using pointers in the C# library results in the expected: Pointers and
fixed size buffers may only be used in an unsafe context. And using the
'ref' keyword doesn't...

I'm sure I'm missing something simple - I do not code in C regularly, and
the breaks are long enough for me to forget.
The situation I have is I need to create an array but I do not know the
dimension until runtime. I pass the pointer to a function which then
determines the size and then creates and populates it. I can walk the array
OK in the function, but the app crashes when I try to do so in the calling
routine.
Here's a small...

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:

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

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...
