Hi, I'm doing an IT degree at university, and my lecturer's do not teach
m$ technologies. I was wondering if anyone could point me to the
implementation of mutex's and semaphores in .net? Or the microsoft
equivalent of them.

Steven,
If you want to see the actual code for the implementation of Mutex,
Semaphore, etc. , download yourself a copy of Lutz Roeder's free Reflector
product, Load MsCorlib, and use the built - in disassembler to see the actual
code in your favorite language.

I'm afraid this will not work for him, since they are implemented in .NET
framework by calling WinAPI.
And Semaphore class is in System.dll, not in mscorlib.

Yes, Semaphore is in System.Dll, and Mutex is in MsCorLib. And even though
WinAPI calls are used, you can still decompile to C# for example and examine
quite easily how everything is implemented, including any DLLImport
signatures.

Hi,
I have some code, to which I added usage of posix semaphores. I am
working on a solaris platform. After doing that, my process becomes
unkillable, that is it will not terminate if sent a SIGTERM signal.
I am not ignoring that signal. Just adding this code related to
semaphores seems to be causing this problem. None of my threads is
sleeping indefinitely on any semaphore wait.
Any help will be appreciated.
If this is not the...

Hi;
In a research project, I want to use shared memory with semaphores.
First I have to create an environment for interprocess messaging. I'm
thinking of having a main process which creates a big shared memory
and manage all messages which are sent by objects inside the
environment. Is this method effective for a high loaded messaging
area? I heard about using ports can cause loss of data.
And, is it ok to have a main process which will...

Hello,
I would like to know if posix semaphores are inter processes or just
semaphores for threads inside the same process.
I have not seen it defined in the posix specification I have found, but
I have maybe missed something.
Thanks in advance.

I have a C# application and a VB6 application that need to share a dialup
connection to the internet. Don't ask why, this is one of those corporate "do
or die" things.
The only way I can see to do this is by using the combination of a MUTEX to
create a Cross-application Singleton for the Dialing operation and a Named
Semphore that can keep a count of how many processes are currently sharing
the connection from the client's workstation...

Hi,
I am using Perl ithreads. The threads I create shall access a shared hash.
In order to control access to the hash, I would like to use a semaphore. (BTW, does the hash need the protection at all if I can make sure that all threads use different keys?)
Semaphores in Perl are provided by the (obsolete?) "Thread" module, which has been replaced by the "threads" module in recent versions. But in the latter, there are only locks, no...

Firstly please excuse the long ramblingness. I need some conceptual help, I am trying to make two programs that are exactly the same but take it in turns to execute something, so the output looks something like the following:

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,...
