Has anyone got any idea how to i开发者_高级运维mplement a rudimentary semaphore in java without making use of wait(), notify() or synchronize.I am not looking for a solution to this problem just a poi
Is it ok if 开发者_StackOverflowfew/couple of processes access semaphore concurently or semaphore should be accesed mutualy exclusive?Well, that\'s the purpose of semaphore - to be safely accessible f
I would like to know if Boost mutexes and semaphores store any infor开发者_StackOverflow中文版mation on the disk, or if there is an option to avoid that (e.g. storing the data in a memory block).
i wrote 2 processes in order to satisfy mutual exclusion but om not sure if it is.. my initial flag value is 0.
Is it possible (in .net) to have a thread wait for a semaphore to be \"fully signaled?\" Specifically, here\'s what I\'m looking for:
Can I have a sem_t (semaphore) object take a开发者_高级运维n a value of more than 1? Since sem_post only increments by 1. Is there a sem_set?Yes, a sem_t can take on a value of more than 1. You can us
Are 开发者_运维技巧the P() and V() operations that can be performed on a semaphore guarantee atomic? Can a semaphore prevent two processes getting into the P()?Suppose we have a binary semaphore, s, w
I have a code where I am working on a set of 3 semaphores. I have a two sets struct sembuf wait[3],signal[3];
I am trying to achieve something easy to describe, but I cannot find how. I want to be blocked until a list has at least one element. Let\'s say we have two workers.
Below is code in which each thread must wait for each o开发者_StackOverflow社区ther thread to complete the rendezvous part and then wait until everyone has completed the critical section.
