hi,
my multithread application, running under solaris box, is crashing
eventually.
I tried to spot and substitute functions not "thread safe", but I
guess my search wasn't good enough. I have put localtime_r and
asctime_r where I was using localtime and asctime. But I didn't find
any correspondent _r function to "time".Also, I found that "readdir"
is not thread safe. But what about "scandir"?
Thanks for any help

OleDbCommand class like many .NET classes has the following description in
its help file:
"Thread Safety

between "unnamed data slot "and "data slot".and docs in Thread.GetData()
say "Threads use a local store memory mechanism to store thread-specific
data." what is "thread-specific data"?

We are evaluating some old code that was written as part of our math
library.
This code uses some optimizations that I'm not sure are necessary or
safe, but is a source of debate between my coworkers.
Method 1 includes a temporary storage varriable at class scope.
Method 2 includes a temporary storage varriable at method scope.
Method 3 includes a temporary static storage varriable at method scope.
Are any of the methods better than...

Below are three classes for a console application. If put into three
separate files, the sub main() will launch multiple threads adding and
removing the same value. At the end we expect the value for all
Balances to be 0. When using an Integer things work fine. LONGS do
not.
We are using the Interlocked methods. I believe the Interlocked.Add
method is not thread safe when using longs on 32bit systems.
We are aware of...

I was often noted by Thread Safety declarations when I was reading .NET Framework Class Library documents in MSDN.
The declaration is usually described as 'Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.'
So, does this mean All the static/shared methods written in .NET compatible programming language, such as C#, VB.NET, are guaranteed to be...

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,...

Hello
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...
