I noticed that when I\'m performing a wait operation on a condition variable, it immediately returns. The consequence is that, when executing the following dummy code, 100% of one CPU is being used in
It\'s written in POSIX threads tutorial https://computing.llnl.gov开发者_如何学编程/tutorials/pthreads/
A while back I was thinking about how to implement various synchronization primitives in terms of one another.For example, in pthrea开发者_开发知识库ds you get mutexes and condition variables, and fro
If a thread calls pthread_cond_wait(cond_ptr,mutex_ptr) will a null cond_ptr, is it guaranteed to not fall asleep?
The following code reproduces the error: #include <iostream> #include \"boost/thread.hpp\" #include \"boost/date_time/posix_time/ptime.hpp\"
A multi-threaded piece of code accesses a resource (eg: a filesystem) asynchronously. To achieve this, I\'ll use condition variables. Suppose the FileSystem is an interface like:
I have a multi-threaded application that is using pthreads.I have a mutex() lock and condition variables().There are two threads, one thread is producing data for the second thread, a worker, which is
I’m reading up on pthread.h; the condition variable related functions (like pthread_cond_wait(3)) require a mutex as an argument. Why? As far as I can tell, I’m going to be creating a mutex just to
Here is the typical way to use a condition variable: // The reader(s) lock(some_mutex); if(protected_by_mutex_var != desired_value)
For some concurrent code, I want to connect a bunch of signals together like a circuit. In .NET we can do a WaitAll or WaitAny on a collection of signals. I want to do something like this:
