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...

I have a requirement to run two separate postmasters on the one machine. It
looks like they compete for resources (semaphores) so won't run
concurrently.
I compiled twice, specifying different ports and home directories:

--prefix=/usr/local/teprpg01

Hi,
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:
setup semaphores, etc

proc 1 doing first thing
proc 2 doing next thing

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

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 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...
