Re: Atomic semaphore in 'C' on HP UX If you look at the Linux sources for PA-Risc, you'll find a fast lock implementation in inline assembly. That will work fine also in HP-UX, although I don't know how to do inline assembly with HP C. You can compile the function in question...
May be, due to similarity in their implementation a mutex would be referred as binary semaphore. Strictly speaking, a mutex islocking mechanismused to synchronize access to a resource. Only one task (can be a thread or process based on OS abstraction) can acquire the mutex. It means there ...

This semaphore API has a pure userland implementation which does not involve any system calls nor block any operating system threads. It works closely with the event model of NGINX without introducing any extra delay. Like other APIs provided by thislua-resty-corelibrary, the LuaJIT FFI feature...
For comparison, an implementation using only one queue and pipeline barriers is in the computeDrawCommandsGctOnly function in timeline_semaphore_main.cpp.Note that for both the computeDrawCommandsTwoQueues and computeDrawCommandsGctOnly code path, we are using a separate submitFrame function to do ...

This is a followup to #3573. We have now received the first user feedback from @jebeaudet which exhibits the same behavior as in the previous issue. We have tried with Maven 3.8.x from the maven-3.8.x and Resolver 1.7.1 with Redisson's R...
in that it does not require this information. The implementation of the priority ceiling algorithm takes into account the scenario where a task holds more than one binary semaphore. The holding task will execute at the priority of the higher of the highest ceiling priority or at the priority of...
