I have been studying internals of Java for quite some time. I am curious to learn and understand how threading/locking takes place in Java.
This is my first attempt on semaphores and threads. I constructed this code from examples and the man pages found on the Net.
I am using following code to limit use of resources. Once in a while(after 3-4 days of successful run) I get queue empty exception or the returned object is found to be null.
The following code runs perfectly well on my XP SP2 machine开发者_开发技巧, but the call to WaitForSingleObject waits indefinitely when running on my Vista machine:
I have multiple apps compiled with g++, running in Ubuntu.I\'m using named semaphores to co-ordinate between different processes.
Can every imaginable synchronization probl开发者_Python百科em be solved with judicious use of semaphores? What about weak semaphores?No.Just for example, it\'s impossible for a system that uses only s
Is it possible to query a s开发者_如何学Cemaphore created with sem_get without actually blocking like the sem_acquire function does?
Perhaps it\'s too late at night, but I can\'t think of a nice way to do this. I\'ve started a bunch of asynchronous downloads, and I want to wait until they all complete before the program ter开发者_
When dealing with threads (specificallyin C++) using mutex locks and sem开发者_如何学编程aphores is there a simple rule of thumb to avoid Dead Locks and have nice clean Synchronization? A good simple
There are two queues of children waiting to use a roundabout in a playground – one is facing it from the north, one from the south. Children may only enter the roundabout from the front of either que
