In order to familiarize my self with Flash files and their bytecode I've
started to make an assembler. My first problem is writing the bitfields
the format uses often. It is a series of fields, each can be a different
number of bits, combined into the least amount of bytes possible. Extra
bits in the last byte are padded with zeros. I would like to make a
function that takes a size and value for each field needed, calculate
the amount of...

Hello all,
I have recently been porting code from Linux to cygwin and came across
a problem with static const class members (discussed below). I am
seeking to determine whether I am programming non-standard C++ or if the
problem lies elsewhere.
To summarize static const class members are not being accessed properly
when accessed from a DLL by another external object file (not within the
DLL). It only occurs when the static const...

Hi all,
I follow c.l.c. for only a short time and I would like to know
why there isn't anything concerning bitfields among the FAQs.
Is it because ...
1. of portability issues?
2. bitfields aren't enough useful to be discussed?
3. of the low frequency of questions concerning this topic?
4. of anything else?...

Hi,
In my couple of years of experience, I have never found a single
instance where I needed to use unions and bitfields(though I have used
structures).I was just imagining where would these find
relevance.Though both of these(bitfields and unions) are used where
space is a constraint(so I can assume always in embedded systems,where
memory is particularly less)and we want to save space/memory.
As far as I have read, there is no...

Hello C Group,
From what I remember, it is implementation dependent the way that a
compiler may order bitfields in a struct. In the example program I give,
Solaris Sparc gives one result, Intel x86 gives another result (for the
GCC compiler).
Is there a portable way to test how this information is stored? In
particular, will the result of the program below always result in c
being 0x01 or 0x80? Does the compiler allow for padding so...

Hi all,
I've recently been following the object-oriented techiques discussed
here and have been testing them for use in a web application. There is
problem that I'd like to discuss with you experts.
I would like to produce Javascript classes that can be "subclassed"
with certain behaviors defined at subclass time. There are plenty of
ways to do this through prototyping and other techniques, but these
behaviors need to be static and...

Hello,
Here is some code mixing bitfields and longs in an union.
Any comments on the validity and portability of this program ?
Thank you very much.

printf("%d:%d:%d",dt.day,dt.mon,dt.year);
In the above code the members of the structure are bitfields. we are trying to print those values using %d. "%d" is actually used to retrieve an integer of 2 or 4bytes accorind to the wordsize of the CPU, but here it is of 5,4 or 12...

Who can explain to me what bitfields are and how to use them in
practice? I would need a fairly detailed explaination, I would be a
newbie to advanced C programming features. What are the advantages of
using bitfields?

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,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

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.

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...
