Hi,
I am trying to stub out debug log messages in my application, if
the logging subsystem is not enabled.. For e.g a invocation
#define LOGMSG !Logger::Enabled() ? false : Logger::LogMsg
so that
LOGMSG("Log Me\n");
will be a NO-OP if the Logger::Enabled() returns false, else the

Hi guys
I want to insert a load of pieces of data into a map
The map has an std::string representing a field name as the key, and the
value is a struct with 2 members - the field length and a bool
indicating whether the field is a special field or not.
The struct representing the value has a constructor that takes a single
parameter for the length, and defaults the boolean to false.

Where should I use them?
I am giving you my understandings. Please correct me if I am wrong:
MACRO:
e.g.:#define ref-name 99
The code is substituted by the MACRO ref-name. So no overhead.
Execution is faster. Where will it be stotred?(Is it in bss/stack/?)

Hi,
I have the following which fails with "disagreement in number of macro
arguments" when compiling with Imagecraft ICCAVR. Has anyone got any
ideas - its not vital but would make the code a lot nicer to read:
#define SET(x,y) (x |=(1<<y))
#define PIEZO PORTB,5

Hello, there's another languages that can do a macro substitution, how can I
do this in Csharp.
This is an example of what I want to do
Dataset ds = new Dataset;
string a = "ds";

I think "macro substitution" is the correct term for what I want to do, but,
to be sure, here is a description of what I'd like to know is possible:
I want to be able to create a create an object of a type whose name is
stored in a constant. For example:
Const FORM_NAME_1 as String = "frmThisForm"
Const FORM_NAME_2 as String = "frmThatForm"

hi guys,
Can you please suggest that in what cases should a macro be
preferred over inline function and viceversa ? Is there any case where
using a macro will be more efficient as compared to inline function ?
thanks for any help in advance ...

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,...

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...
