I'm trying to write a program that's run on both Windows 98 and Linux.
I need a timer, that I can start and when it hits a limit, it needs to
call a callback function. I also need to be able to abort the timer
before it hits the limit - it's the classic timeout type thing.
I'll readily admit I'm no expert on C++, but after a trawl of the WWW
pages, there appears to be two solutions depending on whether it's Linux
or Windows.

Hi all,
does anyone know how to generate a millisecond delay in C, compiling
under Linux? I understand the function sleep() will generate a delay
down to a resolution of one second, but I need to be able to refine
this to milliseconds.
Any ideas?
Thanks in advance,

I am developing a .net application using C# that requires a 1ms timer. I
have tried creating said timer by creating a timer object
(System.Timers.Timer) that is seeded with a 1ms interval. I have also tried
creating a thread with a 1ms sleep time.
The timer object that was created will only yield a resolution as low as
10ms no matter how low the interval is set.
Most of the time the thread timer yields the same 10ms resolution as the...

I want to write a benchmark that will measure performance of several
different algorithms for the same problem. There is a set time bound
though, the algorithm cannot run longer than n minutes.
Here is what the main program would do:

Hi all,
I know it may sound like dump newbie question (which is very much
true, as I am a newbie, not even a real programmer), but I need to
implement a calendar time clock with a millisecond resolution. For
hours I've been digging the Visual C++ 6 help and Googling like a
madman. It seems to me that the standard C just don't have the tool to
get this type on information. Sure I found the time() and the clock()
but they don't really...

Hi,
Im trying to time some parts of my code using the Stopwatch class,
but it is so slow, I tried the QueryPerformanceFrequency()
but this seems to be just as slow,
if I just simply call this function in a loop it takes 21 ticks
with a reported frequency of 3.5mhz
its is about 6us wich is over 12k instructions on my 2ghz cpu.
this negates the idea of having a high res timer ...

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'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...
