Is std::queue thread-safe?

What differences between queue, deque and priority_queue? And under what situations choose one of them to use? Thanks for your help!

Hi, When I try to compile the following program, I get the following error: $ g++ anotherTest.C anotherTest.C: In function `int main()': anotherTest.C:47: void value not ignored as it ought to be What I am trying to do is that I have a global queue. I create an object of class "testClass" and then add it to the queue. My question

Hi, can I tell e.g. a queue that it should re-allocate 512 elements each time it comes to it's boundaries? -- -Gernot int main(int argc, char** argv) {printf ("%silto%c%cf%cgl%ssic%ccom%c", "ma", 58, 'g', 64, "ba", 46, 10);}

I wrote a simple, but proprietary queue class that efficiently enqueues and dequeues arbitrary length byte arrays. I would like to replace it with an STL container if the performance overhead is not too high. Currently, I am thinking of replacing it like shown below, but it is not efficient due to repeated function calls to "push". Can anyone with more STL experience show a better way to use it, if there is one? // CUSTOM QUEUE //...

Hi Guys, I've done a mulithread queue implementation on stl<queue>, my developement environment is on VC6 as well as FC3. Let's talks about the win32 side. The suspected memory leak is find after I've run through my unit test cases. Test Case:

Hello everyone, I decided to pick c++ back up after not really having used it much in 10 years. Just as a point of refference, there was no standard C++ last time I used regularly. Anyways coming back, I've fallen in love with all the improvements in the language such as the STL. Congrats to anyone who worked on it, you did an excellent job.

I am writing a C/C++ program that runs in background (Linux). Therefore, normally no output would be written into standard output. However, sometimes I want to have debug message collected and sent tho network to a client so that errors and debug messages can be displayed simultaneously anywhere. I tried to use a std::stringstream to do the job. I created the stringstream in main() and pass it as pointer into a few threads. Those threads...

Hello I have a Queue which is declared as, std::queue<unsigned charm_Queue; I push data into this queue. Now i want to take the data out of this queue using Iterator.

Hello I am working on a design in which there is a Queue which will read data from a database. This happens in one particular class. Class CRecieveData { std::queue<unsigned charm_RxQueue; }

I've read a bit online seeing that two writes are not safe, which I understand, but would 1 thread push()'ing and 1 thread pop()'ing be thread-safe? Basically my situation is the follows: --Thread 1-- 1. Reads TCPIP Buffer 2. Adds Buffer to Queue (q.size() to check queue isn't full, and q.push_back(...)) 3. Signals Reading Thread Event & Goes Back to Wait for More Messages on TCPIP

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...
