For a homework assignment i need to program the following scenario. This is going to be done using semaphores using BACI (which is C--)
Follow up question to my pervious question: Conditional wait with pthreads I changed my code to use semaphores instead of mutex locks and conditional signals. However, I seem to have run in to a cond
Check My Understanding of semaphores, please! I understand the idea behind counting semaphores and bina开发者_运维问答ry semaphores. However the difference between a spinlock and semaphore implement
I wanted to know what would be better/faster to use POSIX calls like pthread_once() and sem_wait() or the dispatch_* functions, so I created a little test and am surprised at the results (questions an
the only thing i understood is semaphore is a pri开发者_如何学Pythonmitive way critical region has a GUARD variable(semaphore also does but the name is not GUARD!)
I have this requirement wherein I have to increment the value of a POSIX semaphore by more than 1. Apparently, there is no way in POSIX specification to do this. There is no sem_setvalue() similar to
If I do not define LINUX_ENV macro,everything goes well(especially,the IPC_RMID cmd return 0). but if I define LINUX_ENV(I am running on linux system-ubuntu10.04),the last semctl\'s IPC_RMID cmd retur
I am a new bee to MAC/OSX. I am working on Titanium a cross platform runtime, which uses POCO library for most of the portable C++ API. I see that POCO uses POSIX semaphore for its NamedMutex implemen
I\'m porting some old C++ project on Linux (RHEL 5.3). The situation is the following #include <semaphore.h>
I use SysV shared memory to let two processes communicate with each开发者_高级运维 other. I do not want the code to become to complex so I wondered if I really had to use semaphores to synchronize the
