As it currently stands, this question 开发者_如何学Gois not a good fit for our Q&A format. We expect answers to be supported by facts, references,or expertise, but this question will likely so
I was wondering if someone can tell me what would be the best way to bring my application to the foreground if a mutex was not able to be created for a new instance.
Are the two code samples below equivalent? Poco::ProcessHandle::PID ProcessRunner::processId() const { Poco::ProcessHandle::PID pid = 0;
Suppose that a process is creating a mutex in shared memo开发者_Go百科ry and locking it and dumps core while the mutex is locked.
I have the following piece of code in thread A, which blocks using pthread_cond_wait() pthread_mutex_lock(&my_lock);
I have a desktop application that runs on a network and every instance connects to the same database.
Ok, I was running POV-Ray on all the demos, but POV\'s still single-threaded and wouldn\'t utilize more than one core.So, I started thinking about a solution in BASH.
I read somewhere (can\'t find the page anymore) that lock free data structures are more efficient \"for certain workloads\" which seems to imply that sometimes they\'re actually slower or the gain fro
I have a multi-R/W lock class that keeps the read, write and pending read , pending write counters. A mutex guards them from multiple threads.
I am creating an application that implements inter process communication. For this purpose I have set up a shared buffer, which seems to work fine.
