in msdn document,there is a paragraph titiled "Thread Safety", why

Hello all; I'm trying to debug an issue with a java script called, SelectSockets. It appears to be a fairly common one found on the web. I downloaded the SGI Java v1.4.1 installation from SGI's webpage and installed it using SGI's swmgr application. The installation was very straight forward and there were no errors when I installed the package. Then I ran /usr/java2/bin/javac SelectSockets.java to make the SelectSockets.class file.

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

Hello everyone, I am a VC++ programmer. When i develop a multi-threaded application in C++, I prefer to use worker thread, so that the main thread and worker thread can communicate using messages.(i will prefer to use PostMessage than SendMessage API in order to avoid any dead locks ) I prefer to post messages to a thread , instead using call back functions(passing pointer to another thread's function.)

In my application I have two threads. Each of them creates a new propertygrid. In the property grid I have a property with a color editor. Whenever i am clicking on the combo box to change the 'Color' in the first thread is fine. Any other thread that tries to modify the color in the property grid throws: "Controls created on one thread cannot be parented to a control on a

Hi, Sorry for a repeated post but i didn't receive an answer and will try to re-phrase my question: How do i close an additional thread from the main thread, if this additional thread is stuck waiting for a blocking operation, eg. if in this additional thread i wait for a Tcp connection: Socket s = tcpListener.AcceptSocket();

I have a second thread, t2, that errors out and will stop. It's status is then "Stopped". I try to start t2 from thread 1, t1, by checking If t2.threadstate = "Stopped" Then t2.start() However, this throws and error: System.Threading.ThreadStateException: Thread is running or terminated; it can not restart.

I thought I need something like this, but it turns out I don't. I'm still interested if this can be done: Can you do a multi-thread "lock", that locks out everything else, all other threads, without explicitly locking out those other threads? For example, can you take a single section of code, without changing any other code at all, and make it so that when it executes, it is the only thing executing?

Hello, i'm trying to program a thread that would be locked (by a mutex) and that would only be unlocked once that a function (generating data) is done. The purpose is to generate data, and unlock the mutex in order to activate the thread once the data is generated. I have to do it this way, i can only call the thread if the data are generated. ******************************************************** step 1: initialize the mutex

hi, i get Exception in thread "main" java.lang.NullPointerException when i run my application. the exact error is: "Exception in thread "main" java.lang.NullPointerException at sortmergejoin.MergeJoin.Field(MergeJoin.java:204) at sortmergejoin.MergeJoin.SMJoin(MergeJoin.java:84) at sortmergejoin.MergeJoin.<init>(MergeJoin.java:34) at sortmergejoin.Main.main(Main.java:24) Java Result: 1"

Most computers default to English, but sometimes we require a different language, especially when relocating. Forgot to request a specific language before your computer shipped? No problem! You can effortlessly switch the default language on Windows 10 without reinstalling. I'll walk you through it. First, let's disable language synchronization. With a Microsoft account, language settings sync across devices. To prevent any complications,...

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...

Dear forum friends, With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers. The idea...

The next Access Europe User Group meeting will be on Wednesday 1 May 2024 starting at 18:00 UK time (6PM UTC+1) and finishing by 19:30 (7.30PM). In this session, we are pleased to welcome a new presenter, Adolph Dupré who will be discussing some powerful techniques for using class modules. He will explain when you may want to use classes instead of User Defined Types (UDT). For example, to manage the data in unbound forms. Adolph will...

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...
