Here I am the Writer worker thread, I want to know if the main Reader thread has reached the PrepDone state. And below I am the reader, there I wan ...
There is all sorts of documentation online and in books that say that you should always use a while loop as opposed to an if statement when using cond ...
In a spare-time project of mine, I'm implementing a duplex transcoding framework. The most essential functions I'm writing are Read and Write function ...
While waiting on a condition variable, the thread changing the state of the predicate must own the lock, so the update isn't missed during the wakeup. ...
Problem I think I'm misunderstanding the CV-Mutex design pattern because I'm creating a program that seems to not need a mutex, only CV. If someone c ...
I write a demo about condition_variable. I need the correct order to be first-second-third, but there comes to the deadlock.Program infinite loop and ...
In trying to create an asynchronous I/O file reader in C++ under Linux. The example I have has two buffers. The first read blocks. Then, for each time ...
We were trying to create C++ code that would read a block from a file, and start a thread to asynchronously read the next block while processing the f ...
I'm having trouble thinking of a way to properly implement a signalling mechanism for multiple listeners waiting in the same function for a producer t ...
I have a question on the interplay between condition variables and associated mutex locks (it arose from a simplified example I was presenting in a le ...
As far as I know, only condition_variable.wait_for with predicate(because double check inside) could avoid to be unblocked by spurious wakeup, but not ...
with c++11. As std::notify_all would cause spurious wakeup, then why std::notify_all is remained but not std::notify_one all the time? And could std:: ...
I'm looking at the following snippets: and thread_f: My understanding of the above code is, that main grabs the lock, creates the thread and run ...
std::atomic<T> and std::condition_variable both have member wait and notify_one functions. In some applications, programmers may have a choice b ...
A longer version of the title question would be: On my machine, sizeof(std::condition_variable) is 72 bytes. What are these 72 bytes used for? ...
I tried to code Producer and Consumer Problem but after producing up to a certain value -(val) produce thread ends. but the consumer thread's conditio ...
My thread does not need to be locked. std::unique_lock locks thread on construction. I am simply using cond_var.wait() as a way to avoid busy waiting. ...
I want to run multiple threads every 100ms. In order to achieve that I thought of introducing std::mutex and std::condition_variable. The problem I'm ...
I have cpp code where one thread produces, pushing data into a queue and another consumes it before passing it to other libraries for processing. W ...
My program has a segment that is similar to this example. Basically, there are 3 threads: inputer, processor, and outputer. I found that busy wait u ...
