Hi all,
I need to know, what is the difference between dynamic memory
allocation, and stack allocation ?
1. If I have a class named DestinationAddress, when should I use
dynamic memory allocation to create object of that class ?
2. If it says "dynamic memory allocation", is it mean the
following code :
DestinationAddress* dest = new DestinationAddress(); // code 1

why not to build
a malloc_m() and a free_m() that *check* (if memory_debug=1) if
1) there are some errors in bounds of *all* allocated arrays
from them (and trace-print the path of code that make
the error and exit) just when malloc_m and free_m start.
(I use a 1100 static array for write the path (like a queue)
of called function, operator, etc and write using '+' where is
find the memory error)
2) if the pointer to free is alredy...

Hi All,
I realize this is not a Palm OS development forum, however, even though
my question is about a Palm C program I'm writing, I believe the topics
are relevant here. This is because I believe the problem centers
around my handling of strings, arrays, pointers and dynamic memory
allocation. Here is the problem I'm trying to solve:
I want to fill a list box with a list of Project Names from a database

Hi,
My C code (running on Soalris Unix) has some "segmentation fault"
that I wish to use purify to do it. I poked around the web, and found
some information about adding some lines in a Makefile file to use
purify. However, my code is a rather simple single-source C program,
and I didn't write a Makefile for it.
I'm wondering if anybody can tell me which commands are to be
entered at the Unix prompt to use purify. And, I don't know if...

In C programming, I want to know in what situations we should use
static memory allocation instead of dynamic memory allocation. My
understanding is that static memory allocation like using array is
faster than malloc, but dynamic memory allocation is more flexible.
Please comment... thanks.

i have some doubts on dynamic memory allocation and stacks and heaps
where is the dynamic memory allocation used?
in function calls there are some counters like "i" in the below
function. Is this stored in stack. If yes whether it will be deleted
on exiting from the function.
is dynamic memory allocation needed for this purpose

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.
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...
