Hi
I´m wondering why there are so few examples with Semaphore.
Is it obsolete?
I´ve got a Class Data.
It offers 2 Threads methods for updating, editing, .. a private
dictionary.
Now I have to make sure, that both threads are synchronal,

Hello,
I am trying to write a multithread program that simulates producers and
consumers. My program can have many producers and many consumers (each in a
separate thread). It has a storage place (buffer) with "n" capacity. The
user provides these parameters on startup. The buffer works with a circular
queue.
It's a console application. My implementation is working with Semaphores
to synchornize everything. I think it's synchornized...

I tried using a Semaphore class (have included the full listing
reproduced from article Figure 1 at the end of this email) in .NET 1.1.
It works fine most of the time, however, I see the following error
occassionally:

Too many posts were made to a semaphore in mscorlib.

Hello all,
I m facing a memory related problem with semaphores. Our business
application uses semaphores extensively and the limit imposed by the OS
on the number of semaphores that can exist on the system is only 128.
This could be increased to a higher value but that would not be a
permanant solution to my belief. We are using the sem_get, sem_acquire
php functions. After the use we are releasing the semaphore by using
sem_release.

To make it simple, I have a simple test C program which calls my
semphore library functions only. (It doesn't call any db2 function at
all). And the following is the test program:
#include "hasem.h"
#include <semaphore.h>
#include <stdio.h>

I'm having trouble creating a Semaphore with read-access rights for
everyone. Originally I was trying to use this code:
semaphore = new Semaphore(maxLocks, maxLocks, "RwLock#" + name);
but when using that code to create a Semaphore instance for an
existing system semaphore (i.e., the second time the code gets hit), I
get an UnauthorizedAccessException. So I tried specifying that
everyone has read rights:

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

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,...
